Abstract
Zn1-xMgxSe mixed crystals were grown by the high-pressure Bridgman met hod in the x range 0.06 to 0.285. X-ray investigations show that with increasing Mg content the transition from a sphalerite structure to wu rtzite occurs at x = 0.185 +/- 0.03. After annealing in liquid zinc or zinc vapour, investigated crystals exhibit n-type conductivity as wel l as blue-violet and orange photoluminescence in the temperature range from 40 K to room temperature.
