Hybrid Plasmonics

JPEGHybrid plasmonic benefits from the coupling of plasmonic states with molecular electronic, excitonic or vibrational states in order to enhance the near-field interactions and to enable their exploitation for various applications : photo-voltaic, photo-catalysis, plasmo-electronics, enhanced spectroscopies (IR, SERS, TERS), sensing. This topic is developed in collaboration with material synthesis labs. in particular in the United States (university of Rice, Houston) and in France (L2C/Annealsys/IEM Montpellier, LAAS-CNRS Toulouse) and in the frame of Labex-NEXT and regional projects (DIMENSION 2019-2021).
