Optical properties and sensing in plexcitonic nanocavities: from simple molecular linkers to molecular aggregate layers.

We present a theoretical study of a metal-molecular aggregate hybrid system consisting of a strongly coupled dimer connected by molecules characterized by an excitonic transition. The plasmonic resonances of the metallic dimer interact with the molecular excitations giving rise to coupled plasmon-exciton states, so called plexcitons. We compare the… CONTINUE READING
