Paper Abstract

This work presents results of investigations of photoluminescence and structural properties of ternary Zn1-xBexSe, Cd1-xMgxSe, Zn1-xMgxSe and quaternary Cd1-x-yMgxZnySe, Zn1-x-yBexMgySe, Zn1-xMgxSe1-ySey mixed crystals. These crystals were grown from the melt by the high-pressure Bridgman method. Zn1-xMgxSe and Zn1-xSrxSe were also obtained by annealing of ZnSe crystals in evacuated quartz ampoules containing Mg or Sr metal. It has been found that admixing of Mg into ZnSe favors the formation of wurtzite Zn1-xMgxSe while Be-sphalerite Zn1-xBexSe structures. Low temperature (40 K) photoluminescence spectra consist of exciton, edge and deep levels emission bands. For most of investigated crystals the emission corresponding to the highest photon energy line in luminescence spectrum is observed up to room temperature.
