Paper Abstract

Recently, wide gap II-VI mixed crystals are studied for their application in technology of blue-green laser diodes. The mixed crystals were growth using the modified pressure Bridgman method. The temperature, absorption and excitation study of Zn1-xAxSe mixed crystals using Raman scattering method is reported. Measurements have been performed for crystal with x equals 0.07 for A equals Mg content and x equals 0.09 for A equals Be content. From the Raman spectra the longitudinal optical (LO) and transverse optical (TO) modes which correspond to ZnSe-, MgSe- and BeSe-like single crystals were distinguished. For all used excitation wavelengths and different temperatures the integrated intensities of LO and TO modes using a curve-fitting method have been calculated.
