Molecular plasmonics and nanophotochemistry

Leading scientist: Davy Gérard

Summary

In this research topic, we aim at using the intense and confined electromagnetic fields around optical nanoantennas to control light-matter interactions at the nanoscale. For instance, nanoantennas can be used to enhance the fluorescence emission from quantum emitters, to detect nearby molecules, or to trigger photochemical reactions. We hence work on the design and fabrication of nanoantennas (either plasmonic or dielectric), on functionalization techniques to graft molecules on nanostructures, and on experimental techniques to characterize the optical response of the resulting hybrid systems (including extinction and scattering spectroscopies, near-field optical imaging, and photochemical imaging).
