Kinetics of energy exchange between a quantum dot and a spherical nanoparticle with a plasmonic shell

A theoretical study of the dynamics of energy exchange in a two-level system consisting of a spherical nanoparticle with a dielectric core and a metallic shell and a quantum dot in the weak confinement mode is carried out. The system geometric parameters are determined at which the interaction of the Vanier-Mott exciton of a quantum dot with the electric field of localized plasmons of a nanoparticle becomes strong. It is shown that with an increase in the intensity of the plasmon-exciton interaction, the nature of the kinetics of energy transfer between the components of the system changes from aperiodic attenuation to damped oscillations.
