The aim of the project is a comprehensive theoretical and experimental study of the effect of crystalline deformation around active transition metal ions Cr2+ and Fe2+ located in binary ZnSe and ternary Zn1-xMgxSe, Zn1-xSxSe, and Zn1-xCdxSe single-crystals on their photoluminescent properties. In particular, studying tendencies towards broadening the spectral range of luminescence and increasing Fe2+ PL time decay dependence on temperature. The integrated application of these methods will allow us to determine the magnitude and types of local distortions of the crystal field caused by doping and investigate the influence of structural defects, which lead to the modification in the experimental optical spectra.
