Abstract

A universal theoretical model explaining the effect of the shift of absorption and emission bands of transition metal ions in solid solutions of semiconductor compounds is proposed. By the example of ternary compounds Zn1-xMgxSe:Cr2+ and Cd1-xMnxTe:Fe2+, an estimate of the typical parameters of the long-wavelength shift of absorption and luminescence in the mid-infrared range with increasing of concentration of solid solution is performed. A generalization of the effect to the case of multicomponent solid solutions is considered.
