Team web page

Plasmonic nanoparticles (NP) behave as nanosources of light, heat and charge carriers. Their morphology is a key parameter because the ultra-fast deactivation of plasmon takes place following competitive relaxation paths, whose relative weight depends on the morphology of NP and its environment. Gold nanohybrids (AuNP/chromophore) have a strong technical and societal impact. They are linked to energy, environment and health, in particular cancer therapy (*HEPPROS project) through the generation of reactive oxygen species (R. O. S) and heat.

Our activities focus on the synthesis and assembly of high quality gold nanoparticles, with various sizes and shapes, in order to provide suitable materials for research in Plasmonics, Medical and plasmon-induced nanochemistry. These nanostructures are studied in collaboration with teams of experts to discover unexpected properties.

 [1988 -2008] ∎ Photophysics and Photochemistry

 

At the interface between optical spectroscopy and quantum chemistry

We have studied many photoinduced reactions such as fluorescence, the formation of triplet states, energy transfer, electron transfer (Marcus theory), the formation of T. I. C. T. states, photoisomerization, photoconductivity, photocatalysis, photoionization, UV damages of DNA, excitonic states, solvatochromism by combining time-resolved spectroscopy and quantum chemistry.
