Abstract
This paper presents results of investigation of photoluminescence (PL) and cathodoluminescence (CL) as well as Raman scattering in Zn1-xMgxSe mixed crystals grown by high pressure Bridgman method for 0 less than x less than 0.615. The crystals exhibit yellow-green and blue luminescence from 40 K up to room temperature. The intensity ratio of 'blue' band to the deep levels band increases with increasing magnesium content. Cathodoluminescence microscopy was used to examine the spatial distribution of luminescent centers in a sample. CL images of crystals surface at various wavelengths that correspond to different maxima in the CL spectra were obtained. Raman polarized spectra of Zn1-xMgxSe were measured at room temperature (RT). The dependence of phonon energies on composition can be quite well described by the modified random element isodisplacement model.
