Abstract

This work presents results of investigations of photoluminescence and structural properties of ternary Zn_1-xBe_xSe, Cd_1-xMg_xSe, Zn_1-xMg_xSe and quaternary Cd_1-x-yMg_xZn_ySe, Zn_1-x-yBe_xMg_ySe, Zn_1-xMg_xSe_1-ySe_y mixed crystals. These crystals were grown from the melt by the high-pressure Bridgman method. Zn_1-xMg_xSe and Zn_1-xSr_xSe 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 Zn_1-xMg_xSe while Be-sphalerite Zn_1-xBe_xSe 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.
