Bulanyj M. Spectroscopy of solid solutions crystals on the basis of zinc sulphide

Spectroscopy of crystals of solid compounds on the basis of zinc sulphide doped Mn, Al, Fe, Cr and other impurities. The purpose of researches: to find out of a role of impurity centers (Mn, Al, Cr, Fe, Ag, Cu) and other defects during recombination in monocrystals of solid solutions of Zn (1-x) Cd (x) S and Zn (1-y) Se (y) at external effects (ultra-violet and infrared excitation, monoaxial pressure, plastic deformation, static and variable electric fields) in a wide interval of temperatures for forecasting of optical and electrical parameters of crystals and creation of materials with forecast properties. Methods of researches: an electronic paramagnetic resonance, photo - EPR, optical detection of a magnetic resonance, optical spectroscopy, method of crystal growth from a melt under a pressure of an argon. The spectrums of optically detecting magnetic resonance in crystals of Zn(1-x)Cd(x)S for the first time are researched. The electro field constants and constants of spin - phonon interaction in cr ystals of solid solutions are defined. The localization in a crystal lattice of ions of manganese, chrome and iron is placed. The change of a charge state of Fe(3 +), Cr(+), A - centers under an operation of infrared illumination and their parameters was found. It was found also, that it is possible to change structure of zinc sulphide and solid solutions on its basis with the help of a plastic deformation over a wide range to change. The optimized technologies are recommended for cultivation and doping of crystals of solid solutions on the basis of zinc sulphide.
