Temperature Dependences of Mn2+ Photoluminescence with Different Local Surroundings in ZnS Single Crystals

Photoluminescence spectra of Mn 2+ in ZnS single crystals were recorded in the range 77–623 K at different activator concentrations and exciting radiation wavelengths. Spectra were decomposed into individual bands, each of which corresponded to radiation of manganese centers with a certain type of l...

More Information
Summary:Photoluminescence spectra of Mn 2+ in ZnS single crystals were recorded in the range 77–623 K at different activator concentrations and exciting radiation wavelengths. Spectra were decomposed into individual bands, each of which corresponded to radiation of manganese centers with a certain type of local symmetry. The obtained results made it possible to estimate the effect of activator concentration and temperature on changes in the number of radiating manganese centers with different types of local symmetry relative to all luminescent Mn 2+ in ZnS single crystals with different excitation wavelengths. The results are explained in terms of the redistribution of direct optical and resonant mechanisms of energy transfer of the exciting light to Mn 2+ taking into account losses due to nonradiative interaction with the ZnS single-crystal lattice.
