Rare earth ions doped upconverting nanoparticles (UCNPs) are luminescent nanomaterials with the ability to convert low energy (infrared) photons into visible and ultraviolet radiation through energy transfer, cooperative and excited state absorption mechanisms. The IR excitation can be done with low-cost diode lasers and provides great advantage to the use of UCNPs in biological applicati…
This proposal aims to develop new micro and nanostructured luminescent materials based on ra-earth ions (TR:Sc, Y, La-Lu) with applications in the energy area, health, telecommunication, radiation detection, and safety. Different strategies will be undertaken to develop new luminescent materials focused on the energy converter area, such as i) Molecular light-converting devices through th…
Through fundamental research on structure-property relations, using complementary simulation, spectroscopic and functional characterization methods, we will map the "genome" and develop new active glasses and glass-ceramics with promising applications. For that, the core group of the Center will comprise 13 professors at USP and UFSCar (both located in São Carlos) who are experts in engin…
At the Laboratory of Spectroscopy of Functional Materials (LEMAF) in IFSC/USP, we carry out interdisciplinary research in the field optical and luminescent materials for photonic and biophotonic applications. Among the targeted materials are: 1) Glasses and glass ceramics doped with trivalent rare earth ions TR3+ for scintillators, solar concentrators and sensors; 2) Host-guest hybrids ba…
Nowadays, the shortening in accessibility of safe drinking water is a matter of worldwide concern due to various contaminants released into water bodies from industrial, human and animal sources, including microbial pathogens, which can be of greatest health concern. The use of chemical reagents like chlorine and ozone for disinfection of drinking water is widespread but results in disinf…
This proposal seeks to enhance electron injection, electron transport and optical absorption of nanostructured TiO2-based solar cells in order to improve their power conversion efficiency. Therefore, we propose TiO2-graphene nano-hybrid, featuring high electron transport, for the manufacture of efficient solar cells. TiO2-graphene nano-hybrids with various TiO2: graphene weight ratios are…

The development of remote thermal sensors has attracted much attention in the last decade for temperature monitoring in the microscopic level for the control of biological functions, detection of fires, monitoring of corrosive and electromagnetic environments, etc. Among the possibilities for remote measurement, emphasis is given on the optical techniques that rely on spectral changes ind…
The project aims to prepare and characterize glasses of mixed fluorophosphate systems based on gallium phosphate, with alkali and alkaline earth metal fluorides (MF and MF2), codoped with silver and rare-earth ions to obtain luminescent nanoclusters of silver distributed through the glass matrix through thermal treatment of the samples and also through the laser photostructuring process, …
The increasing global energetic demand makes the development of durable, efficient and environmentally friendly materials of paramount importance. Particularly, luminescent ceramic materials raise a lot of attention due to the possibility of an ample variety of applications as in light emitting devices (LEDs), emergency lighting, biomarkers, radiation detectors, etc. The incorporation of …
The current world scenario facing to the growing energy demand and increasing of global pollution makes pivotal to research new durable technologies with high efficiency and low ecological impact. The development of luminescent ceramic materials has been particularly attractive, mainly due their wide possibility of applications, such as LEDs, emergency signs, medical biomarkers, radiation…

For a long time, cancer and bacterial infectious have been among the major causes of deaths worldwide. Despite enormous developments in the fields of diagnosis and treatments, there is still an urgent need for generic, accurate and point-of-care platforms capable of enabling the rapid and precocious diagnostics of such diseases in order toallow faster and more adequate treatment. In this …
O objetivo deste trabalho é fazer novas contribuições no desenvolvimento e implementação experimental de poling térmico de vidros para geração de respostas ópticas não-lineares visando aplicações no campo da microfotônica. O poling térmico é uma técnica que envolve a aplicação de um campo elétrico forte a um substrato de vidro aquecido abaixo de sua temperatura de transição vítrea (Tg). …
Perovskite solar cells (PSCs) have attracted great interest for rapidly growing light-to-electricity conversion efficiencies, already exceeding 22%, although they still lack high stability, especially in air and humidity. In this project, novel solution-processed oxide semiconductor materials will be prepared and characterized towards applications as hole- and/or electron-transport layers…
The present proposal is based on two research fronts: i) the preparation and characterization of new materials based on copper (I) halide complexes for luminescent applications in lighting and gas sensing; ii) the design, synthesis and characterization of materials based on quantum dots and upconversion nanoparticles dispersed in solid host matrices. The Cu(I) complexes synthesized in our…
