Organic and inorganic quantum wells in a microcavity: Frenkel-Wannier-Mott excitons hybridization and energy transformation

We investigate polariton states in a cavity containing organic and inorganic quantum wells (QW) when the energies of 2D Frenkel exciton in the organic QW and of a semiconductor Wannier exciton are near the energy of the cavity optical mode. We show that interaction through cavity photons creates mixed hybrid Frenkel-Wannier-Mott-cavity photon excitations. We show that the new hybrid states can be tailored to engineer the fluorescence efficiency and relaxation processes. We perform illustrative calculations demonstrating, in strong coupling regime, the appearance of a Wannier exciton relaxation by emission of an optical phonon in the organic QW.
