Recombination of localized defects through their hopping motion is considered. An essential difference in the behavior of charged and uncharged defects has been established. In the former case, random electric fields, created by charged defects, shar

The formation of polaritonic states, shifted to both sides from the initial exciton level by about 0.1 eV, was observed through luminescence of solid xenon samples consisting of small crystalline grains. Unlike previous works, where the observed red

It is shown that intrinsic vibrational degrees of freedom, inherent in two-atom exciton and hole polarons, drastically affect their transport properties in wide-band dielectrics (rare-gas solids and alkali halides). A fast excitonic energy transport

The theory of a conventional small-radius polaron, i.e., a self-trapped excess electron or hole in a dielectric or semiconductor, describes a hopping motion with overcoming a barrier whose height is near the polaron binding energy E b (assumed to be

The excitonic mechanism of energy transport from a host crystal to impurity is of different character for narrow excitonic bands of organic dielectrics and for a broad band inherent in some inorganic dielectrics. Unlike the former case, the latter pr

The mechanism of radiation changes involves both the formation of vacancy clusters (pores) from photoproduced vacancies and the optical manifestations of pores. The growth of pores is controlled by dislocations (serving as sinks for interstitials gen

Spectroscopic study of excitons in molecular chains (S120 J-aggregates), formed in a solid matrix, disclosed well-pronounced features which cannot be described by the conventional theory of exciton dynamics in a strictly one-dimensional system: the e

Absorption spectrum, related to creating excitons with nonzero wave vector inside a wide band, is considered for an insulator crystal with lattice defects. It is shown that the main contribution to absorption is determined not by the scattering secti

It is known that in rare-gas and alkali-halide crystals the excitons exist both in a free state and in the form of excimer two-site quasi-molecules. Due to mixing of the states of two types, vibrational levels of excimer quasi-molecules turn to narro

For some class of crystals, an excited atomic state gives rise, along with free excitons, to another related type of crystalline excitations also formed by resonance bindings, viz. an excimer two-atomic quasi-molecule. Such an exciton polaron, due to
