thermal and optical ionization energies of the trapping centers were determined. It was shown that the difference in optical and thermal energy depth of traps exceeded significantly that in ZnS and might serve as a characteristic of the ionic coupling degree of a compound.For most trapping centers the photothermal mechanism of charge release by optical stimulation was revealed.Complex investigations of Sr
