Optical spectroscopy
Florian Massuyeau (IE)
Optical absorption: spectra obtained in transmission or in diffusion or specular reflection from 200 to 3300 nm. Quantification of the color of materials (CIE, Lab, ...); Gap Measurement; Transparency measure; Determination of thickness and calculation of index on thin films.
Stationary photoluminescence: emission spectra of 300 to 1600 nm and excitation of 200 to 700 nm. Declines of luminescence from ms to several hours. Analysis of the emissivity of materials; Quantification of energy transfers; Quantum yield calculation.
Time-resolved photoluminescence: 3D mappings in the UV-Vis domain for declines from ns to ms.Analysis of the emissivity of materials; Modeling of luminescence declines to quantify energy transfers; Extinction of luminescence, Excitonic annihilation processes.
