Outstanding instruments
The transient absorption experiment measures the changes in the visible absorption spectrum of a sample, liquid or solid, induced by a femtosecond laser pulse on a time scale ranging from a hundred femtoseconds to a few hundred picoseconds
Action spectra are an increasingly important part of semiconductor photocatalyst research. This translates the photonic efficiency as a function of the excitation wavelength. The action spectrum of a photocatalytic system allows identifying key aspects of the mode of action during photocatalytic reactions
Héméra is a center of linear and nonlinear optical spectroscopy dedicated to the non-invasive multi-scale analysis (molecular, nanometric, micrometric) of the physico-chemical properties of materials surfaces and interfaces between materials, whatever their nature (metal, semiconductor, insulator, (bio)molecules) or their physical phase (solid, liquid, gaseous)
Time-resolved microwave conductivity (TRMC) is an excellent technique for the investigation of charge-carrier dynamics, at nanosecond and microsecond time scales, through the sample photoconductivity perturbation upon pulsed laser excitation
