摘要：
This work deals with the study of photoluminescence properties of ZnxMg1-xSe epilayers grown by molecular beam epitaxy on (001) GaAs and (111) ZnTe substrates and ZnxMg1-xSe layers obtained by thermal diffusion of Mg into ZnSe single crystals. Luminescence spectra of ZnxMg1-xSe lasers are dominated by blue and violet emission bands with maxima positioned in the range of photon energies: 3.05-3.28 eV, 2.88-3.04 eV, 2.81 eV and 2.705 eV, depending on preparation conditions. In some samples the blue luminescence is observed up to room temperature.
