The National Institute of Photonics – INFo activities are dedicated to the study of
Photonics in Micro and Nanostructured Systems.
Photonics is a research area that has developed in the last decades after the invention
of the laser. With respect to its more modern and contemporary aspects, Photonics is
intimately related to Nonlinear Optics (NLO). Initially, NLO developed as a fundamental
research area, where people would search for the understanding of the interaction of
radiation with matter in a regime of high intensities. Ten years after its birth, the
international effort in this area had already revealed the great potential for application of
the known phenomena and related techniques. Presently, there still exists a large interest
in the identification of new phenomena and in the development of new spectroscopic
techniques based on the nonlinear behavior of matter. On the other hand, there are several
applications arising from basic research that are actually developed in hundreds of
research labs and industrial installations.
Research in NLO has made it possible for a wide variety of interdisciplinary activities
that stimulate, for instance, Photonics and their applications. Examples of Photonic
applications can be found in several branches of activities. Concrete applications are
related to the development of new materials which present adequate optical response to
be used as sensors or light emitters, the development of new lasers, optical limiting
systems, all-optical switches, optical memories, devices for optical communications and
biophotonics applications (involving basic studies of microscopy or applied to areas such
as Dentistry, Dermatology, Ophtalmology, and so on).
The association among the laboratories that form the National Institute of Photonics
– INFo, are making it possible to face challenging problems that demand higher
investment in human resources. Another advantage of the articulations in the Institute is
the availability of more equipments and the infrastructure that can be shared by the
participant groups.
The Institute has available equipped laboratories to fabricate new photonic materials,
equipment for structural and thermal characterization of materials, equipment for
processing the produced samples, lasers, and acquisition, control and data processing
equipment, allowing the realization of several experiments simultaneously. Furthermore,
due to the activities under development, the laboratories are equipped to immediately
start the study of some of the new problems and themes, in areas such as new materials,
communications, optical devices, plasmonics and biophotonics.
The formation of a multidisciplinary team, involving physicists, chemists, engineers,
and biologists have important consequences in the quality of the research as well as in the
approach and solutions of the problems under investigation.
The research being made present wide and up-to-date interest not only for the
evolution of basic science, but also for applied areas such as Materials Sciences,
Materials Chemistry, Communications Engineering, Biology and Health Sciences.
The most relevant social contribution of the INFo has been the formation of human
resources. This is an inherent activity to the Institute, due to the fact that most of the
laboratories are located at Universities. Even the associate laboratories at
CLA/IPEN/CNEN, CBPF/MCT and CETENE/MCT, located at Research Institutes, have
strong participation or contribute to graduate programs at USP-SP, CBPF and UFPE,
respectively.

The student`s formation occurs in a very diversified manner, since the professors at
the INFo teach at undergraduate and graduate levels.
At the undergraduate level all members of the INFo working at Universities have
acted directly in the High School Teachers and Bachelors degree courses in Physics,
Chemistry, Mathematics, Electrical Engineering, Odontolgy, Pharmacy, Biophysics and
Biomedical Engineering, besides interaction with high schools through the training of
high school teachers and visits of high school students to the research laboratories.
At the graduate level, the members of the Institute have contributed to Master and
Doctorate programs in Physics, Chemistry, Materials Sciences, Engineering and
Dentistry at their Institutions. Graduate students from all over the Country have been
performing their thesis and dissertations through the laboratories associated to the INFo.
Several students from neighbor countries are also attending graduate programs in Physics
Chemistry and Materials Science at the INFo laboratories.
Project Management
Cid B. de Araújo (Coordinator) and Sergio C. Zílio (Vice – Coordinator) are
responsible for the execution of the project.
Purchases of equipments are centralized at UFPE, as well as travel expenses.
Equipment, consumables and services are acquired in accordance with the initial plans
presented by each participating laboratory. A considerable fraction of the resources is for
Interchange of the members of the Institute, aiming to make plain use of the existing
research facilities. This is done through visiting periods for researchers and students in
the various laboratories, for cooperative research projects. The financial support for
travels is mainly for students, post-docs, and professors from the emerging centers that
form the team project. International trips to present the results of research in Congresses
are also supported.
Authorization for the expenses not included in the original plan is preceded by
analysis of the Managing Committee composed by C. B. de Araújo, A. S. L. Gomes, S.
C. Zilio, N. D. Vieira Junior, L. C. Sampaio Lima, and Y. Messaddeq.

Research lines and Sub - projects
Micro and Nanostructured Photonics Materials
Sub-Project A: Synthesis and Nonlinear Optical Spectroscopy of Hybrid
Micro- and Nano-Structured Materials.
The synthesis of various hybrid materials and their NL optical properties were developed.
The optical techniques for characterization of the materials were luminescence, pump-probe and
Z-scan techniques, employing nano-, pico- and femto - second lasers. Several results on organic –
inorganic materials have been obtained as can be observed in the publication list.
A.1) Metallic nanoparticles in colloids and polymers.
The work developed was focused on new methods to synthesize optically active materials.
Silver nanoparticles (NPs) growth within polyesthers was thermally and photochemically induced
leading to nanocomposites in which the resulting color depends on the particles’ size and
aggregation. Silver nanoparticles with nearly the same the size were synthesized in five different
carrier media in systems with the same composition, proving that the “solvent” effect is not a key
factor if the experimental variables are properly set. Silver colloids synthesized were used to
assemble random lasers and allowed the investigation of the solvent effect on the linear and nonlinear properties of Ag NPs. The NL optical properties of gold nanoshells synthesized were also
investigated.
We also developed new methods to synthesize flourescent lanthanide - organic framework
and binuclear lanthanide coordination compounds and used a photochemical route to synthesize
hybrid material based on the conducting polymer polyaniline and polyphosphate gels, which were
used to assemble electrochemical capacitors.
Ag/poly(esther-co-styrene) nanocomposites
A.2) Multifuncionality on silica glass. Advanced nanostructured coatings.
Photochromic windows, IR and/or UV pumped white light emitting films and luminescent
mesoporous sensing materials are the main functional activities that we have considering to add
to silica glass substrates through nanostructured coatings.
Photochromicity is being achieved by the utilization of the known redox pairs W6+/W5+,
6+
Mo / Mo5+, and Ti4+/Ti3+. Hosts considered in the films fabrication include cellulose derivatives
and vegetable oils based organic - inorganic hybrids and polyurethanes. The light activated redox
phenomena is studied as a function of the films and metal containing nanoparticles chemical nature
9
IR and/or UV pumped white light emission is being achieved by the deposition of nanoparticulate
films based on rare earth compounds, mainly vanadates and tellurites. The triads Eu3+-Tb3+-Tm3+ and Yb3+Ho3+-Tm3+ have been considered for UV and IR pumping respectively, with the emitting colors being tuned
by the rare earth relative compositions and also the chemical nature of the nanoparticles.
Finally, mesoporous silica films have been obtained by dip - coating together with Evaporation
Induced Self Assembly (EISA). Mesoporous thin films constitute a platform for special luminescent and
Raman sensors and luminophors by incorporating rare - earth compounds and colloidal metal particles in
the ordered porous structure.
Sub-Project B: Vitreous composites containing metallic nanoparticles.
Vitreous composites containing metallic nanoparticles based on germanate glasses were
studied. Growth of ~1000 % in the photoluminescence intensity corresponding to the 614 nm
transition of Eu3+ doped GeO2 - Bi2O3 glasses was observed. Also the influence of metalic
nanoparticles (gold and silver) on electric-dipole and magnetic-dipole transitions of Eu3+
demonstrated that the magnetic response of metal – dielectric composites at optical frequencies
can be as strong as their electric response due to the confinement of the optical magnetic field.
Phenomena related to frequency upconversion and energy transfer processes among rare-earth
ions in germante and tellurite glasses with metallic nanoparticles codoped with Yb3+/Tm3+,
Yb3+/Er3+, and Tb3+/Eu3+ were studied. The influence of the intensified local field in the vicinity
of the nanoparticles and/or the energy transfer processes among the nanoparticles and the rareearth ions were identified as the origin of the enhanced optical response of the nanocomposites
studied.
GeO2-PbO nanostructured thin films were also produced with the sputtering technique and
had their nonlinear properties studied. The nucleation of silver or gold nanoparticles was
performed using appropriate heat treatment procedures. The increased nonlinear susceptibilities
due to the influence of localized surface plasmons make these films useful for devices such as
displays, optical limiters ans all-optical switches.
Sub-Project C: Optical spectroscopy of transition-metal-ion-doped
glasses.
We have investigated Ni– and Bi–doped glasses that might present infrared broadband
luminescence. We started by studying glasses with compositions 60(NaPO3)3–40Al(PO3)3–NiO
and 60(NaPO3)3–40Al(PO3)3–Bi2O3 produced by the melting-quenching method in N2
atmosphere. Two samples of each composition were prepared, and then one Ni– and Bi–doped
glass was annealed at 450oC under H2 atmosphere during 4 hours. The unannealed glasses do not
exhibit any luminescence under excitation at 475 or 808 nm, while the annealed ones present
broadband emission (0.9–1.5 µm) that originates solely from the glass surfaces given that no
luminescence is observed after the surfaces were re-polished. The preparation method of these
glasses must be improved as well as other compositions will be evaluated.
Sub-Project D: Pure and rare-earth doped transparent vitro-ceramics.
D.1) Chalcogenide based glasses and glass – ceramics.
Transparency in the IR, high linear refractive index, low phonon energy and high non-linear
susceptibility are the main intrinsic characteristics of chalcogenide and chalco-halide glasses. In
this part of the project we have chosen the base system Ga2S3-GeS2. These glasses are good hosts
for optically active lanthanide ions. Moreover, addition of CsCl leads to the preparation of
10
transparent glass-ceramics under selected thermal treatments. In this way glasses have been
prepared in the systems Ga2S3-GeS2-CsCl, Ga2S3-GeS2-AgCl, Ga2S3-GeS2-CsCl-Ag2S and Ga2S3GeS2-CsCl-AgCl.
Transparent glass-ceramics have been obtained displaying permanent second order non linear susceptibility (crystal phases - AgGaS2 e AgGaGeS4) and also relatively strong emission
properties of lanthanide ions (Pr3+ and Er3+ added to the initial compositions) were obtained.
D.2) Generation of wide color gamut visible light in rare-earth doped nanopowders.
Novel materials suitable for the development of solid-state red – green - blue (RGB) light
emitters have drawn much scientific and technological interest lately, as the basis for future high
brightness full - color display technology, back lighting, assay of biological compounds, remote
sensors, optical data storage, optical printing, etc. A significant number of methods have been
employed in the past few decades, exploiting for instance dye - laser systems, LED/OLED
technology, and frequency upconversion luminescence in lanthanide doped materials. Recently,
multicolor upconversion emission and white light generation was produced in novel glasses and
oxyfloride nanostructured materials. The latter find potential applications in general lighting
appliances, and integrated optical devices. Therefore, it is of great interest, to study frequency
upconversion processes in alternative phosphors materials and identify the major relaxation and
interaction mechanisms of rare - earth ions implanted into the matrices. Considering solid - state
hosts, nanoglasses have recently emerged as a viable alternative for photonics and biophotonics
applications. They are obtained by a suitable heat treatment of the precursor glass samples
produced by standard oxide glass fusion and casting methods. Such heat treatment yields the
precipitation of nanocrystals in which rare-earth ions are selectively concentrated. The crystal
sizes are small enough to allow light transmission with no considerable scattering loss. The
advantages of the nanocomposites reside in the fact that the rare-earth ions are confined in nanoscaled crystalline environments of low phonon energy, producing high quantum efficiencies and
low optical absorption cross sections when compared to vitreous environment. In order to avoid
the technical demands and difficulties of either crystals or glass preparation exploiting
conventional melting methods under controlled atmosphere and high temperatures, the sol-gel
process was used. The sol-gel technique is one of the most widely used methods for production of
bulk materials and thin films in integrated optics, because it is simple, low cost and performed at
room temperatures, and possess the ability to control the purity and homogeneity of the final
materials on a molecular level.
Multicolor visible light emitting NIR-excited Tm/Ho/Yb-codoped tantalum oxide
nanopowders were produced and tested as new phosphor materials. The generation of wide color
gamut fluorescence in glass-ceramic with orthorhombic Ta2O5 nanocrystals dispersed into
amorphous silica-based matrix was observed. Multicolor simultaneously emitted fluorescence
consisting of blue (480 nm), green (540 nm) and red (650 nm) upconversion signals in the
SiO2:Ta2O5 system doped with holmium and thulium and sensitized with ytterbium, was
observed. The proper choice of the rare-earth content and the NIR excitation power yielded the
generation and control of the three primary colors and allowed the emission of a balanced white
or tunable overall luminescence from the glass-ceramic nanopowders
D.3) Luminescent features of novel sol-gel derived lanthanide multi-doped nanostructured phosphors for white LED.
Solid-state light sources for lighting purposes, are of great scientific and technogical interest
owing to their wide variety of benefits over daily used incandescent and fluorescent systems, with
advantages ranging from energy consumption to environmental issues. Amongst various
11
approaches, light - emitting diode (LED) based white light sources are regarded as the next
generation solid-state lighting technology since the realization of white LEDs. This is due to the
fact that they possess valuable properties including low power consumption, high electrical
energy to light conversion efficiency, long life, low-cost and easy maintenance. Moreover, they
have environmental advantages because their production does not require emission of green house gases (CO2), and provokes no mercury pollution. Essentially, there exist two approaches to
produce white light employing LEDs. The first is by color addition using LEDs producing the
three primary (red, green, blue), or a combination of complementary colors light. The second is
obtained by the combination of emission from a blue or ultraviolet LED excited downconverted
light from phosphor. In particular, white LEDs produced by means of a combination involving a
blue or ultraviolet LED and a yellow emitting phosphor, has attracted a great deal of interest
recently, owing to the low cost, easy fabrication process, and high brightness emission. However,
this approach suffers from low color rendering index due to two color mixing, and the generated
white light changes either with excitation power or temperature. To overcome these deficiencies,
a white LED fabricated via UV-blue excited red, green, and blue - emitting phosphors is required.
Thus, one demands for novel phosphors that may produce high downconversion efficiencies and
allow suitable combinations of rare-earth activators that can diversify the emission wavelengths.
Rare - earth (Eu3+, Sm3+, Tb3+, Sm3+/ Tb3+, Eu3+/ Tb3+) doped oxyfluoride 75SiO2: 25PbF2
nano-structured phosphors for white-light-emitting diodes were synthesized by thermal treatment
of precursor sol-gel derived glasses. Room temperature fluorescence emission spectra of Eu3+,
Sm3+, Tb3+, Sm3+/Tb3+ and Eu3+/Tb3+ ions incorporated into low-phonon-energy PbF2 nanocrystals
dispersed in the aluminosilicate glass matrix and excited with UV (395 nm) and blue (405 nm)
light emitting diodes was investigated. The luminescence spectra exhibited strong emission peaks
in the red (600, 610, 650 nm), green (540, and 560 nm) and blue (485 nm) wavelength regions.
White-light emission was observed in samarium and terbium activated phosphors employing UVLED excitation. The dependence of the luminescence emisson intensities upon annealing
temperature, and rare-earth concentration was also evaluated. The results indicated that there exist
optimum annealing temperature and activator ion concentration in order to obtain intense
emission light with higher color rendering index. Therefore, results suggest that the
nanocomposite phosphor herein reported is a promissing contender for white-light LED
applications
Sub–Project E: Fabrication and characterization of composite materials
for Nano-Photonics and Bio-Photonics.
E.1) Vegetable oil based organic-inorganic hybrids and polymers.
The so-called green chemistry includes the preparation of new compounds by using
precursors obtained by self-sustainable, non-polluting processes. In this sense the vegetble oil
chemistry is being considered in the last years for the preparation of new multifunctional
materials.
Castor oil displays interesting and unique functional groups among the different vegetable
oils. In this way it can take part in several chemical reactions leading to new organic-inorganic
hybrids and polymers.
New polyurethane polymers- Polyurethane polymers are widely used in different areas and
castor oil based polyurethanes will for sure enlarge the field of applications. For example highly
luminescent samples have been obtained by including in the polymer composition highly
lluminescent Eu3+ compounds.
New organic-inorganic hybrids- The utilization of the ricinoleic acid and the amino modified
siloxane has lead to new hybrids where the connection between the organic and the inorganic
12
phases are performed by an amide group. These new hybrids are called therefore "amidosils".
Mechanical and also optical properties can be tuned by playing with the chemical compositions of
these new multifunctional materials.
E.2) Multifunctional bacterial cellulose membranes. New SERS sensors,
photo/electroluminescent materials and substrates for flexible organic LEDs
Bacterial cellulose (BC) also known as biocellulose, is produced by strains of
Gluconacetobacter xylinus bacteria in the form of highly hydrated (hydrogels) membranes. BC
and plant cellulose present the same chemical structure. However BC has a pure cellulose
network composed of a random assembly of ribbon shaped fibers less than 100 nm wide. The
unique properties provided by the nanometric structure have lead to a number of commercial
products including dietetic fibers, headphone membranes, special papers, textiles, medical
applications including temporary skin substitution, contact lenses, and optoelectronic devices (epaper, OLEDs).
We are interested in multifunctional materials based on BC, metallic nanoparticles and
lanthanide based luminescent compounds
By using pectin as stabilizer/reducing agent mixed Au-Ag nanoparticles have been prepared
with colours, and therefore plasmon energies, covering all the visible part of the spectrum as a
function of the relative Ag-Au contents.
Multifunctional membranes have been prepared by the incorporation of metallic
nanoparticles and different lanthanide compounds.
Two main properties have been exploited with positive preliminary results: 1- the utilization of
the new active membranes as new SERS sensors for adsorbed species and 2- enhancement of the
luminescence of adsorbed lanthanide compounds due to interaction with the metal NP plasmons.
Concerning the flexible substrates new transparent multifunctional Organic-Inorganic Hybrids
(OIH) have been prepared from bacterial cellulose membranes (BC) and boehmite – GPTS
(glycidoxipropylsilane) system. SEM analyses reveal either a bi-phase (by careful control of the
layer by layer assembly of the two components) or a typically “sandwich structure” formed by
BC microfibril and boehmite-GPTS systems. BC-hybrid membranes display higher transparency
(90% of the light) than pure BC ones (40% of the light) in the wavelength range of 300 to 800nm.
Conductive membranes were obtained by ITO deposition. FOLEDS were obtained by the thermal
evaporation of a copper phtalocianine (CuPC) / N, N’-diphenil-N,N’-bis(1-naftil)(1,1’biphenil)4,4’diamine (NPB)/ aluminum tris(8-hidroxiquinolinate) (Alq3) and an aluminum contact.
Emission characteristics were observed to be similar to the ones observed for the same device
obtained with a glass substrate.

E.3) Nanocomposites (conducting polymer)/(metallic nanoparticles)
The work was dedicated to the investigation of the so-called ELINOR (from Enhanced
Luminescence of Organic-Inorganic Origin) effect, first identified by our group in
polypyrrole/gold nanoparticles. During the last year we have confirmed that the synergic
interaction between the metal and the conducting polymer chains that leads to the enhancement of
the luminescence also exists when different metals (Ag and Cu, besides Au) and other conducting
polymers such as polyaniline (PANi) and PEDOT (a polythiophene derivative), besides
polypyrrole (PPY) are used. In each case, upon ultraviolet excitation the maximum of
fluorescence is observed in different frequencies of the visible region, and we have used factorial
planning to determine the optimum preparation conditions that lead to maximum fluorescence
emission. As an example, while the estimated quantum yield (Φ) for Au microparticles is
negligible (~10-10-10-9), and for specially shaped Au nanorods increases to ~10-4-10-3, our
Au/PANi composites exhibit Φ ~101. The synergy of the metal-polymer interaction is confirmed
once one realizes that Φ ~10-3 for pure PANi, and that the nanocomposite’s fluorescence intensity
is affected by the pH of the medium in a complementary manner to the PANi conductivity. We
have also initiated work directed towards the use of an identified Förster resonance energy
transfer (FRET) regime in co-solutions of (conducting polymer)/(metallic nanoparticles)
composites and fluorenes in the development of more efficient photovoltaic devices. Finally,
since some of the conducting polymers used are polycations and have a non-specific interaction
with nucleotide chains, we have initiated work dedicated to the use of the ELINOR effect to the
identification of RNA or DNA sequences in solution.

Sub-Project F: Coupling of single nanoscopic emitters to ultra-high
quality factor microcavities.
For this sub-project, the necessary tools for controlling and studying the system – an inverted
confocal optical microscope and a scanning near-field optical microscope, are being fully
developed. A very detailed and mechanically sophisticated project for performing the
spectroscopy of microcavities, as well as experiments on coupling of single nanoscopic light
emitters has been developed and the fabrication is almost finished. An apparatus based on CO2
laser (and appropriated optics) has been set up in order to fabricate the microcavities, presently
only silica microspheres, with diameters ranging from 20 to 300 µm. The last part necessary to
14
the realization of the planned experiments is the mastering of fiber tapers’ production and
characterization.
Sub-Project G: Ultra-high resolution microscopy with single nanoscopic
light emitters.
A home - made probe-scanning inverted confocal optical microscope was projected and
developed. It works with a CW laser emitting at 532 nm, operating in both modes, confocal and
wide - field. When operating in the confocal mode, the lateral resolution is ~170 nm, while when
operating in wide - field it shows either ~37 µm or ~50 µm field, depending on the microscope
objective used (100 NA 1,40 or 60 NA 1,43). The probe scanning is performed with the help
of a commercial piezo XY translator stage (100 µm range), which is controlled by a specially
designed LabView program. The piezos of such translation stage are fed by home - made
amplifiers, that present a stability of 1:105, essential to our purposes.
A home - made scanning near-field optical microscope – SNOM is also under development.
The home – made mechanical parts are ready, and nowadays the feedback loop electronics is
being constructed. We already dominate the SNOM tips and hopefully until the end of 2010 this
home - made inverted microscope will be installed in order to make ultra-high resolution optical
microscopy with single nanoscopic light emitters.
Photonic Devices
Sub-Project H: Microstructered fibers.
Many efforts related to the control of transmission properties of microstructured fibers have
been done, like selectively closing holes of its structure, selective filling of these holes with gases,
with organic solutions or colloids of metal nanoparticles or semiconductor quantum dots.
Recently, the selective collapsing of a part of given holes has also been done, leading to the
demonstration of an integrated waveguide coupler.
Bismuth and lead based original glasses have been explored towards linear and non-linear
optical properties.
The main glass compositions are (in mol%)
(70-x)NaPO3-30WO3-xBi2O3 (x= 1 – 30%)
(75-x)TeO2-15GeO2-xBi2O3-10(K2O-Li2O) (x = 1 – 30%)
(100-x)PbHPO4-xWO3 (x = 1 – 70%).
Bulk samples have been obtained by conventional melting-casting-quenching methods.
Thermal and structural properties have been investigated as a function of the Bi and W
relative contents. Thermal analysis (DSC), vibrational spectroscopy (FTIR spectroscopy and
Raman scattering), 31P and 207Pb NMR and also x - rays absorption (EXAFS Pb LIII) were the
techniques employed. UV-Vis-IR absorption, m lines spectroscopy (linear refractive index) and
Z-scan (at 1064 and 800 nm) were used in the study of the optical properties. Important values
were obtained for n2 at 1064 and 800 nm (∼10-14 cm2/W and ≥ 10-15 cm2/W, respectively) which
allowed us to propose potential application in photonic devices.
The most stable compositions (as determined by thermal analysis) were chosen for the
preparation of optical fibers. Core-cladding fibers have been prepared by a method developed in
our lab called "sucking method", where a liquid core composition is cast in a controlled way in a
cladding tube.
Microstructured fibers have been prepared from cylindrical samples prepared with the chosen
composition. Preforms have been obtained by pearcing longitudinal holes with the desired
15
geometry and size. Samples with up to 60 holes defining 3 concentric rings and a solid triangular
core have been prepared and fiberized. Final fiber and core diameters were 130 and 3 m
respectively. No external polymer coating is applied. The optical characterization of the fiber is
planned for the next activities.
Sub-Project I: Preparation and characterization of optical waveguides
in germanate and tellurite glasses.
I.1) Active waveguides were produced for the first time in Er3+-doped GeO2-PbO-Ga2O3
glass. Channels have been written with a femtosecond laser delivering 800 nm pulses. Optical
amplification was observed at 1550 nm with maximal internal gain of 2.7 dB/cm under 980 nm
excitation and similar to silicate and phosphate glasses codoped with Yb3+ and Er3+. The results
obtained are promising for the fabrication of Er-doped integrated amplifiers based on GeO2-PbOGa2O3 glass.
I.2) Tellurite rib-type passive waveguides were produced with TeO2-ZnO vitreous thin films
deposited by RF sputtering. Plasma etching and lithography processes were employed for the
production of the rib waveguides. Propagation losses of 1.5 dB/cm for 3-5 µ m rib widths are
obtained at 633 and 980 nm. The results obtained suggest that waveguides based on TeO2-ZnO
vitreous thin films are potential candidates for photonic devices applications.
Sub-Project J: Coherent control of nonlinear effects in special fibers.
In the past year we setup a system for shapping the spectral phase components of fs-pulses,
employing a liquid crystal spatial light modulator placed on the Fourier plane of a zero-dispersion
stretcher. Such system was calibrated using frequency-resolved optical gating and common-path
spectral interferometry. The pulse-shaper was used to investigate the coherent control of
nonlinear effects in special fibers mainly by applying a known function to the spatial light
modulator and analyzing the outcome. We were able to observe spectral changes produced in the
supercontinuum generation in photonic fibers and tapers, and now we are studying the thirdharmonic generated in capillary containing noble gases. We also investigated the two-photon
absorption in organic compounds, taking advantage of the multi-photon intrapulse interference
process. We have used two strategies to coherently control the two-photon absorption: (i)
applying a known function to the spatial light modulator and (ii) by using a feedback
configuration controlled by a genetic algorithm. For instance, we studied the role of the detuning
between the molecules’ two-photon absorption band and the pulse wavelength on the level of
control achieved. The use of pulse - shaping to coherent control the synthesis of gold
nanoparticles was also made.

Sub-Project L: Fabrication of polymeric microstructures integrated
with glass nano-fibres. Photonic circuits.
A substantial part of the effort during 2009 was devoted to the establishment of a
microfabircation laboratory. We have used the two-photon absorption induced polymerization
technique to fabricate optical active microstructures, whose properties can be externally changed.
Such microstructures contain optical active organics compounds and polymers, as well as biocompounds. Therefore, they can be used for application ranging from photonics to biology. In a
subsequent step, we were able to produce silica nanowires by symmetrical pulling of standard
optical fibers under controlled conditions (flame temperature and drawing speed). We were able
to demonstrate that the microstructures can be externally excited using nanowires, opening new
opportunities for the development of integrated micro-optical devices.

Magneto-optics and spintronics
Sub - Project M: Magnetization dynamics in nanoestrutures.
We investigate the spin dynamo DC voltage generated in bilayers of ferromagnetic and
normal-metal materials as a combination of the spin pumping and inverse spin Hall effects. By
shining the surface of a series of Ni81Fe19/Pt samples with microwave radiation we were able to
inject pure spin current into the Pt layer by the transfer of spin angular moment. Due to the inverse
spin Hall effect the charge carriers in the Pt layer will be scattered giving rise to an in - plane
charge current. By varying the angle of the in - plane spin polarization we were able to separate
accurately the contributions arising from anisotropic magnetoresistance and from the spin-current
pumped into the Pt layer by the precessing spins of the Ni81Fe19 layer. The data for the spin
pumping dynamo DC voltage is in excellent agreement with a theory incorporating the full
dependence on the thicknesses of the FM and N layers.
An apparatus for optical detection of time-resolved magnetization dynamics has been
implemented. The system is based on a femtosecond laser and has been used to investigate
experimentally coherent magnetization dynamics in thin ferromagnetic films. For this we use
ultrashort pulses from a Ti:sapphire laser to induce the coherent dynamics and to observe its
temporal evolution through a double modulation pump-probe technique. We have performed
Time-Resolved Magneto-Optical Kerr Effect (TR-MOKE) measurements and observed the
transient magnetization in monocrystalline iron films on magnesium oxide substrate (Fe/MgO)
and permalloy (Ni0.8Fe0.2) films on silicon (Py/Si). The films were prepared by sputtering and
characterized by ferromagnetic resonance (FMR). It has been possible to understand the role of
the magnetic anisotropy in the triggering of the coherent magnetization dynamics by ultrashort
18
laser pulses. This system will be employed in the near future to investigate magnetization
dynamics in small magnetic structures to be prepared within this project.
The magnetization dynamics of small - scale systems (nano and microscale) can be observed
in time scales ranging from femtoseconds to hours. Depending on the time scale, different aspects
of the magnetic relaxation can be investigated. A second apparatus also based on the magnetooptics is being constructed in order to measure the dynamics in the nanosecond time scale. The
dynamics is induced applying a magnetic field produced by a stripe line, instead of a light pulse
used in the pump-probe technique. Micro-sized magnetic disks made of soft magnetic materials
(e.g., FeNi), depending on the thickness, can exhibit a magnetic vortex. The vortex can move on
the disk as a result of the excitation, and can have a resonant movement if the excitation is AC.
Resonance measurements were performed for an array of FeNi disks with diameter and
thicknesses of 2 µm and 20 nm, respectively. A resonance centered at 500 MHz was identified
and micromagnetic calculations are being made to investigate the vortex movement and the
dissipation process in further details.
Sub - Project N: Production and optical characterization of active laser
media based on monocrystallyne fibers and nanopowders.
N.1) Single crystal fibers.
We investigated the single crystal fibers growth of pure and Nd3+ and Yb3+- doped
LiLa(WO4)2 - LLW -for optical applications. The experimental results showed that moisture on
stored La2O3 is an issue to be controlled to achieve a single - phase formation after solid state
reactions. Single crystal fibers were grown by the micro - pulling down method and the growth
process was investigated concerning the melting behavior, pulling rates and the meniscus stability
during the fiber pulling. Stable growth conditions were obtained for meniscus height changing
from 60 to 150 microns and pulling rates of 0.06 mm/min. It is important to note that higher
meniscus heights break the stable condition of growth resulting in defects creation in these fibers.
Transparent and uniform single crystal fibers with 30 mm length (LLW and LLW: Nd) and 10
mm length (LLW:Yb) were obtained. Optical characterization demonstrated similar properties
observed on bulk crystals of Nd and Yb-doped LLW. Laser tests will be performed.
.Demonstration of laser action in a single crystal Nd:YLF
N.2) Fluoride Nanoparticles.
KY3F10 and KY3F10: Nd nanoparticles were obtained via the coprecipitation method in
aqueous solution, evaluating the feasibility of its preparation with HCl or HNO3 as solvents. The
preparation was made dissolving the rare - earth oxides in hot concentred acid. After drying most
of the acid, a hot KF+NH4HF2 aqueous solution was added under strong stirring for two hours.
19
The powder was separated by centrifugation, alternated by washing several times with NH4HF2
solution and with methanol. X ray powder diffraction analysis showed that the KY3F10 cubic
phase (Fm-3m) was formed for all syntheses performed with HCl. Additional peaks were found
for doped materials prepared with HNO3. The size of the nanocrystals was related to the
broadening of the diffraction peaks by the Scherrer equation, resulting in about 20 nm.
N.3) Random Lasers.
Two types of random laser media are being investigated: nanopowders of Nd: YVO4 and
rodamina dye containing 200 nm sized rutile particles inside a hollow photonic crystal fiber with
a 70 micrometer diameter core. Pump sources are 100 W diode lasers and a Q-switched,
frequency doubled Nd: YAG of 3mJ, 10 ns pulse duration. In both cases we observed frequency
narrowing at the laser emission frequency as a function of pump power by approximately a factor
of 3 and a clear laser threshold. These results have been presented in a national congress. We are
now concluding a theoretical model that explains the observed laser pulses from the random laser.
This model resulted in a perfect fit of the random laser pulses as a function of pump power and
explains possible loss mechanisms for laser action.
BIOPHOTONICS
Sub-Project O: Diagnostic by Imaging and Sensing.
O.1) Development of polarization sensitive optical coherence tomography (PSOCT)
system.
Optical Coherence Tomography (OCT) is a technique based on low length coherence
interferometry that can perform tomographic images of live structures. Mueller Matrices are
mathematical elements that describe how a media alter the polarization state of the incident light.
Differently of the Jones formalism for polarized light, Mueller Matrices can cope with
unpolarized light and with absorption as well. It was developed in our laboratories an Optical
Coherence Tomography system capable of determining completely and uniquely the Mueller
Matrix of a sample, in depth. In this way many measurements are needed with different
combinations of polarization states of the incident beam on the sample and the reference arm of
the interferometer. After calibrating the system, we used a birrefringent sample with periodic
structure (Scotch tape). One software was developed to solve a matrix linear equations system. As
a result 4x4 matrices of images were calculated. Some of the features, as birefringence were
easily identified in some elements of this matrix. We also decomposed the matrix in three
components (depolarizer, retarder and diattenuation) which allowed understand the sample as a
linear combinations of three optical phenomena.
O.2) Development of optical techniques to study microcirculation
The laser Doppler flowmetry allows safe and noninvasive measurements of the human blood
microcirculation with temporal resolution higher than other methods (e.g., laser Doppler imaging,
Doppler-Optical Coherence Tomography). Fluctuations in the flow signal with frequencies
between 0.005Hz to 2Hz have been studied and related to multiple microvascular control
mechanisms, located at different spectral bands. Wavelet analysis has been used for this purpose.
We are developing alternative methods to quantify (and control) variances each spectral band of
interest (due to the Wavelet limitations for this purpose), seeking for new methods to assess
20
microcirculatory dysfunctions such as endothelial and neurogenic dysfunctions commonly
encountered in diabetes mellitus.

O.3) Synthesis and uses of semiconductor core – shell quantum dots for in vivo
toxicological studies
Strategies for the synthesis of water soluble core-shell quantum dots CdTe/CdS and
CdSe/CdS were optimized in order to minimize size distribution ranges, improve reproducibility,
reduce surface traps and obtain higher quantum yields. Toxicological studies have been
performed for CdS/Cd(OH)2 quantum dots in collaboration with BASF SE (Ludwigshafen,
Germany). In the first part, non-functionalized CdS/Cd(OH)2 quantum dots in water suspension
were used for in vivo toxicological experiments via inhalation and injection in wistar rats. 10
mg/liter of free Cadmium ions were detected in the samples. Despite of this, biochemical,
hematological, histological and studies of the fluids of the animals exposed to the CdS/Cd(OH)2
quantum dots, showed low toxicity levels when compared to other nanomaterials, such as TiO2,
ZnO, and Carbon Nanotubes.
A second stage of the toxicological studies has been carried out, in which CdS/Cd(OH)2
quantum dots were turned biocompatible by the functionalization with glutaraldehyde (0.01%
v/v) and are been used for the same experimental procedures performed with non functionalized
(non biocompatible) CdS/Cd(OH)2 quantum dots. Due to the fact that free Cadmium may induce
side reaction related to its toxicity for in vivo studies, we have been developing synthetic routes
for the production of ZnSe/ZnS quantum dots, which have presented high stability and high
emission intensities.

Sub-Project P: Therapeutics.
P.1) Diagnosis by imaging and therapeutics.
Concentrations above 250 µM methylene blue (MB) present a poor photodynamic effect on
yeast cells inactivation. MB aggregation is directly proportional to its concentration.
Monomer/dimer ratio equal to 1 seems to produce the best antimicrobial effect. The addition of
organic fluids leads to an increase in dimerization even when dye concentration is maintained.
The same fluence in different fluence rates shows dissimilar levels of inactivation on microbial
cells. The increase of the fluence rate shows an improvement on cell photoinactivation and a
higher velocity to generate reactive oxygen species. Core-shell CdSe-CdS quantum dots (QD) are
not lethal to C. albicans regardless of the QD concentration or exposure time. However,
morphological changes were observed.

P.2) Characterization of biological tissues after laser irradiation for the
development of new therapeutic methods in Medicine and Dentistry.
One software was developed to calculate semi-automatically the thermal diffusivity of
materials by using the heat equation with the temperature data taken from an infrared
thermocamera during the material heating. It was possible to identify for the first time that the
thermal diffusivity of dentine for high temperatures (300 °C < T < 550 °C) is not linear and it is
much higher than at room temperature, affecting the heat transmission during laser irradiation.
The µ-FTIR spectroscopy, microhardness and retention of CaF2 analysis of enamel, dentine
and nanostructured syntetic hydroxyapatite irradiated with Nd: YAG or Er:Cr:YSGG laser,
showed that there was carbonate and amide content decrease in all laser irradiated samples. After
treatments the samples were submitted to an artificial caries protocol. The hardness from samples
treated with laser in association with fluoride was less affected compared to those that received
only one of these treatments. This synergic effect between infrared laser irradiation and fluoride
surface treatment is useful for caries prevention and it will be investigated in vivo.
Er: Cr:YSGG laser has ability to cut bone, but the explosive ablation and the resulting heat
may affect the surface. ATR-FTIR spectroscopic analysis showed significant loss of organic bone
22
components mainly collagen, indicating that the laser energy must be chosen carefully because it
interferes in the healing process.
A new treatment method for third degree skin burn is being proposed. OCT and histology
showed that femtosecond laser (0,195 mJ, 4 kHz, 30 fs) successfully ablated and removed the
necrotic tissue from the rat skin burn lesion with 564 µm ±12 µm depth.
Multivariate statistical method of ATR-FTIR spectroscopy is proposed as an alternative
means of screening for the diagnosis of thyroid lesions. Using the clinical data as reference, the
cluster analysis (calculated by the Euclidean distances) revealed so far a separation of adenoma
goiter from other malign neoplasm, with accuracy higher than 99 %. The study comparing
follicular lesion and colloid goiter is under way.

Sub-Project Q: Imaging and Sensing at the Molecular Level.
Fluorescence emission of molecules can be modified by their interaction with metallic
nanoparticles. In particular, we showed that metal nanoparticles can increase the emission of
Tryptophan (an essential amino acid). Enhancement of Riboflavin (a potential drug to
photodynamic therapy) fluorescence by silver nanoparticles was also observed and the increase of
singlet oxygen formation by riboflavin-NP is under investigation.
To explore and to understand the role played by the interaction plasmon - fluorescent
molecule in cells and tissue a new technique for time-resolved fluorescence multiphoton
microscopy is being developed, to generate picosecond and sub-picosecond resolution
fluorescence images without XY scanning. A wide-field multiphoton microscopy setup was
established exploring a 800 nm femtosecond Ti: sapphire laser and a TE2000 Nikon inverted
23
microscope. Images based on multiphoton absorption of Tryptophan and Coumarin were
generated and analyzed. Fluorescence images will be obtained associating the optical-Kerr-gate
technique and the wide-field-multiphoton microscopy. Therefore a virtual lock-in amplifier for
CCD images is under development.

Sub-Project R: Photonics applied to energy and environmental
problems.
This sub-project is not listed in the original proposal. It was motivated by the local demand of
knowledge in the areas of energy and agriculture.
R.1) Optical Spectroscopy as an analytical tool for characterization of Biodiesel
The growing energy demand has led to an enhancement of the environmental problems
associated with the use of fossil fuels. Therefore, it becomes necessary to investigate renewable
energy sources to reduce the environmental impact. In this scenario, biodiesel is a viable
alternative energy because of characteristics as biodegradability and absence of sulfur and
aromatics. Biodiesel are esters that can be obtained from a wide range of oils (edible and non
edible) and animal fats. The conversion of the oil into biodiesel has been achieved by
transesterification of triacylglycerides with short-chain alcohols such as methanol and ethanol in
the presence of a catalyst, leading to a mixture containing biodiesel and glycerin. After the
reaction time, the mixture is allowed to stand in a separating funnel in order to remove the
glycerin. The phase containing mainly biodiesel is rotary evaporated to eliminate the short-chain
alcohol and then it is washed with water to remove residue of the catalyst. Parameters such as
oil:alcohol molar ratio and catalyst content have an effect on the biodiesel production. Other
important aspect to be evaluated is the chemical stability of biodiesel due to its high susceptibility
to oxidation. The oxidation process of biodiesel, which depends on parameters such as
temperature and light exposure, leads to the formation of insoluble gums and sediments that can
block the filter system of fuel injection.
In this context, methods based on optical spectroscopy appear as promising analytical tools
since they may combine low cost, fast and accurate results as well as portability. In this project
we propose to evaluate whether optical spectroscopy can be used as a tool to (i) to monitor the
biodiesel production as a function of parameters such as time reaction and catalyst content, (ii)
investigate the degradation of biodiesel submitted to different storage conditions and
temperatures, and (iii) quantify the biodiesel content in diesel/biodiesel blends since such blends
have been used worldwide because environmental, economic and social advantages.

R.2) Abiotic stress studies via fluorescence spectroscopy in biofuel species.
In the past few years there has been a widespread scientific and technological interest in laser
remote-sensing techniques to investigate the status of terrestrial vegetation. The fluorescence of
terrestrial vegetation consists almost exclusively of the fluorescence of leaves, which account for
the largest surface of plants above ground. Within the plant tissue, visible and NIR light is
absorbed (>80%) by photosynthetic pigments and used to drive photosynthetic light reactions and
associated electron transport reactions to reduce carbon and oxidize water in the Calvin cycle. A
small part of the absorbed light energy is lost during the migration from the pigment antenna to
the reaction centers and are dissipated by a number of non-photochemical processes, including
heat, and re-emission of a small but easily detectable amount (2-5% in vivo) of the absorbed
radiation. This re-emission occurs at longer wavelengths in the red around and far-red spectral
region and is termed as Chlorophyll Fluorescence. In particular, the application of laser induced
chlorophyll (Chl) fluorescence spectroscopy remote-sensing has drawn much attention recently
owing to the noncontact and nondestructive nature of the technique. The technique can be applied
for Chl determination in basic photosynthesis research, agriculture, horticulture, and forestry.
Chlorophyll fluorescence represents an intrinsic signal emitted by plants that can be employed to
monitor their physiological state including changes of the photosynthetic apparatus,
developmental processes of leaves, state of health, stress events, stress tolerance, and also to
detect diseases or nutrient deficiency of plants.
Laser induced fluorescence (LIF) is exploited to evaluate the effect of abiotic stresses (salt
stress) upon the evolution and characteristics of in vivo chlorophyll emission spectra of leaves
tissues of Brazilian biofuel plants species (Saccharum officinarum RB863129 and Jatropha
curcas). The chlorophyll fluorescence emission spectra of the 20 min predarkened intact leaves
were studied employing several excitation wavelengths in the UV-VIS spectral region. Red (Fr)
and far-red (FFr) chlorophyll fluorescence emission signals around 685 nm and 735 nm,
respectively, were observed and analyzed as a function of stress intensity and time of illumination
(Kautsky effect). The Chl fluorescence ratio Fr/FFr, which is a valuable nondestructive indicator
of the chlorophyll content of leaves, was investigated. The dependence of the Chl fluorescence
ratio Fr/FFr upon the intensity of the abiotic stress (salinity) was examined. The results indicated
that the salinity plays a very important hole in the chlorophyll concentration of leaves tissues in
both plants spieces, with a significant reduction in the Chl content for NaCl concentrations
around and beyond 100 mM. Our results agreed quite well with those obtained using
conventional in vitro spectrophotometric methods. The laser induced Chl fluorescence analysis
allowed detection of damage caused by salinity in the early stages of the plants growing process,
and as consequence can be used as an early-warning indicator of salinity stress.
