Abstract: Spectroscopic studies of binary and multicomponent semiconductors of the CdS–CdTe, CdS–ZnTe, and ZnS–CdTe systems are performed. They result in confirmation of the formation of substitutional alloys in these systems (in addition to the results of X-ray diffractometry studies), and the chemical composition of the surface as well as the most important characteristic of semiconductors, theelectron work function, the frequencies of strongest luminescence (impurity and band-to band), the emission maxima, and the possibilities of predicting luminescence properties are determined. Recommendations concerning the use of fabricated materials of definite composition as phosphors are given.
