At object of research - recombination centers and their role in photo-electroluminescence of ZnO crystals and solid solutions based on zinc sulfide. The study of electronic state of impurity luminescence, hyperfine interactions and their connection with the peculiarities of the crystal structure of ZnO, ZnS, ZnSe and solid compounds on a microscopic level using electron spin resonance studies (EPR), photo-EPR and magnetooptics is relevant in terms of development of new optoelectronic devices, laser-active elements and elements of spintronics. Research methods - electronic paramagnetic resonance, visible and infrared aim of this work is to determine the influence of impurity 3d - periodic table of elements in crystals and films of ZnO, ZnS, ZnSe and solid compounds on their basis for decision-fine pryk problems related associated with them techniques, as materials for LED devices, display, solid-state sources of ultraviolet, blue and white light. These data suggest that in single crystals ZnS1-xSex annealed in zinc vapor at a temperature of 950 K for three hours in the spectra of photoluminescence (PL) of these crystals observed a new luminescence band (630 nm). Shown that the electron in excited Mn2 + ions depends on the concentration of activator in the lattice of ZnS, and on the excitation conditions. Based on the investigation of the photoluminescence crystals of ZnS: Mn were conclusions about the local symmetry centers Mn2 +, responsible for radiation (557, 578). Shown that the electron in excited Mn2 + ions depends on the concentration of activator in the lattice of ZnS, and on the excitation conditions. Based on the investigation of the photoluminescence of crystals of ZnS: Mn were conclusions about the local symmetry centers Mn2 +, responsible for radiation ( 557, 578, 600, 616 and 637 nm). The results can be used for the development of new generation electronic devices and their application in organizations and enterprises of instrumentation, machinery, electronics, aviation and space industry. The research results have a scientific interest for research organizations (Institute of Materials Science.
