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-ySy 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 favours the formation of wurtzite Zn₁-xMgxSe while Besphalerite 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.
