Lines of interest:

  • Fabrication and characterization of organic devices (OLED, OFET, OLET, OPV);
  • Electrical and optical characterization of organic semiconductors;
  • Deposition and characterization of organic and inorganic thin films with different techniques;
  • Production and characterization of transparent conductive films and flexible substrates;
  • Spectroscopy and optical characterization of materials and thin films.

  • In the last twenty years the Laboratory of Molecular Optoelectronics (LOEM) has been contributing to scientific knowledge and technological development of the field of ​​Organic Electronics. Significant contributions came through the research of light emitting diodes (OLEDs), field effect transistors (OFETs), photovoltaic cells (OPVs) and other organic devices, including those based on rare earth ions. The activities carried out ranges from basic physics to applied research including devices fabrication. The Laboratory also works on the development of transparent conducting oxides (TCOs), flexible substrates for electronics and sensing. Special attention is given to the use of biocompatible substrates such as bacterial cellulose, for applications in the health sciences area (photodynamic therapy, biocompatible implants for photodetectors, etc.). Another area of ​​research is the use of natural compounds from plants and insects to develop a “green electronics”. Over the years the LOEM was responsible for the development of a scientific and technological capabilities in the field of production and characterization of organic devices well recognized in the country and abroad. The work of our Group has been the subject of news articles and interviews indicating the interest that our research raises in several sectors of Brazilian society and industry.
