Optical Processes in Nanostructured Materials Laboratory

About us

The research activity is focused on the synthesis of nanostructured materials, their optical characterization and developing of various applications in the field of the conversion and storage of energy. Three topics are mainly developed:

  1. Elaboration of synthesis procedures of inorganic micro and nano-particles and their characterization by optical methods.
  2. Elaboration of synthesis procedures of composite materials based on carbon nanotubes/fullerenes and polymers and their characterization by optical methods in order to be used in the field of energy storage and sensors for medicine.
  3. Development of the synthesis methods of chalcogenide and soft materials for applications in the field of sensors, information technology and optoelectronics.

The main methods used for optical characterization of above materials are: Raman scattering including the surface enhanced Raman scattering (SERS), FTIR and UV-VIS-NIR spectroscopy, surface enhanced infrared absorption (SEIRA) spectroscopy, photoluminescence under continuous and pulsed excitation and photoconductivity. A special attention is devoted to revealing some specific optical phenomena in mesoscopic materials such as anti-Stokes luminescence, Coherent Anti-Stokes Raman scattering and coherent backscattering.
