Energy Exchange Dynamics and Relaxation of Excitations upon Strong Exciton–Plasmon Interaction in a Planar Nanostructure of Molecular J-Aggregates on a Metal Substrate

Abstract

The kinetics of energy exchange between the plasmonic and excitonic subsystems in a “metal–dielectric–molecular layer” is studied for a planar composite nanostructure with a strong exciton–plasmon interaction. It is shown that the time dependence of the energy transfer between the components of the system has the character of damped oscillations, which depend on the prepared initial state, a number of relaxation parameters, the Rabi frequency, and the detuning from resonance.
