Abstract

It is known that fluorescence of an atom or molecule in the microcavity can be selectively enhanced or inhibited in dependence on the spectral position of it relatively the cavity resonance due to quantum electrodynamical (QED) effect. Great importance is attached to the spherical microparticles on the base of dye microdroplet or solid glass sphere that act as optical cavity with the set of modes on the morphology dependent resonances. Emission from such particles shows sharp line structure superimposed onto the broadband emission at wavelengths corresponding to the cavity modes. These spectral features have been explained by more high density of photon states at the cavity resonance condition (QED effect).
