Influence of Dislocations Move on Photoluminescence of Mn2+ Ions with Various Local Surroundings in ZnS Single Crystals in the Process of Plastic Deformation

The influence of plastic deformation on the change of the relative number of luminescence centers of Mn2+ ions with various local surroundings in ZnS single crystals at various wavelengths of the excitation light has been thoroughly studied. Taking into account that the emission of each individual photoluminescence band is due to the emission of manganese luminescence centers with a certain type of local symmetry, the use of the decomposition of the experimental photoluminescence spectra of Mn2+ ions in ZnS single crystals into individual bands and the subsequent analysis of changes in the photoluminescence spectra of each individual band allowed a detailed study of the effect of dislocation move on quantitative changes in emitting manganese luminescence centers of various types.
