The optical characterization platform at IPCMS currently brings together several instruments: two absorption spectrometers, a spectrofluorimeter, an optical profiler, two fluorescence lifetime measurement systems, and a photoluminescence efficiency measurement setup. A cryostat and other accessories enable work under controlled atmosphere and temperature conditions. The platform is accessible to all IPCMS staff as well as external researchers working in both public and private sectors. Additional measurement systems are under development to extend the range of activities to other temporal and spectral domains, materials, and photophysical characteristics.
