Research on the Effects of Hydrostatic Pressure on the Electronic States of Impurities.
Abstract
The theoretically predicted shift of vibronic components and change of their distribution under high pressure were confirmed by the low temperature emission spectra of the natural crystal scapolite. The insensibility of the self-activated luminescence in the ZnS : B crystals to the high pressure action indicated that it comes from a tightly associated new luminescence center. The differences between the high pressure action on the cubic and hexagonal ZnS : Mn crystals are interpreted by the resonance energy transfer. The pressure shifts of the excitonic excitation bands in the ZnS and ZnSe crystals agree with the gap shifts calculated for these crystals but are smaller than the experimentally found pressure shifts of the donor-acceptor luminescence bands.
