Based on the configuration coordinate model, the possibility of using individual bands of normal distribution in the photon-energy coordinates to approximate luminescence spectra has been analyzed. The practical application of this approach to ZnS single crystals doped with Mn2+ ions made it possible to obtain photoluminescence spectra of individual bands at various plastic deformations. Taking into account the dependence of the area under the individual band curve on the number of luminescence centers allowed us to trace, in a certain way, the change in the relative quantitative characteristics of radiating manganese centers with various local environments during the plastic deformation process. The obtained results correlate with the results of electron paramagnetic resonance studies, supplement the information on the methods for resolving experimental luminescence spectra into individual components, and do not contradict generally accepted ideas about the photoluminescence mechanisms in single-crystalline materials of the A2B6-type.
