Polaritons of Triplet and Binary Hybrid Structures in a Microcavity

We analyze the properties of a triplet hybrid (semiconductor—organic layer–semiconductor) in a microcavity. Analysis is performed for excitation energies reduced in the triplet from the Wannier–Mott exciton with the highest energy to the Frenkel exciton with an intermediate energy and from the Frenkel exciton to the Wannier–Mott exciton with the lowest energy. The semiconductor components of the hybrid have the form of thin nanofilms; the organic component is represented by the layer of a finite thickness smaller than the diffusion length of the Frenkel exciton. We analyze the frequency dependence of polaritons formed during the general hybridization of the Wannier–Mott excitons, the Frenkel exciton, and the fundamental model of the microcavity. We have obtained the dispersion dependences of polaritons of reduced binary hybrids and the organic layer in the microcavity. Our results can be of interest for studying the energy transfer kinetics with a multiple change in the form of energy in triplet and binary hybrid systems.
