Light/matter interactions

Spectroscopy, photochemistry, non-linear optics, excited states.

Animated by Cyrille Monnereau and Akos Banyasz

The last few years have seen the emergence, within the laboratory and in connection with the major thematic trends of modern chemistry, transversal scientific subjects related to the light-matter interaction in general, and its valuation in the context of photochemical and photophysical processes. controlled. This type of process is at the origin of multiple applications with strong societal challenges, such as the phenomena of conversion of light energy into chemical or electrical energy, the design of molecular machines and quantum memory devices, or the biophotonics. These themes require transversal and complementary skills in spectroscopy, optics, molecular and materials chemistry, modeling of excited electronic states, all represented at the laboratory scale. The emergence of this theme, Light-Matter Interaction, was supported and reinforced by the establishment of a collaborative platform for linear and non-linear spectroscopy. The latter enables increasingly ambitious studies ranging from fundamental spectroscopy and photochemistry to pre-industrial and industrial applications. Recent examples include the development of intelligent luminescent probes, photoactive textile supports, new photocatalysts, microstructured optical devices, etc.
