Abstract

ZnMgSe mixed crystals were obtained by the high pressure Bridgman method and by thermal diffusion of Mg metal into ZnSe crystals. Measurements of luminescence and transmission spectra show that the band-gap energy of such mixed crystals is larger than that of pure ZnSe. ZnMgSe crystals exhibit n-type conductivity and electrical parameters comparable with that of ZnSe. Blue-violet luminescence in the temperature range from 40 K to room temperature was observed. This feature makes this material very promising for future applications in constructing short wavelength electroluminescent devices.
