Title: Optical properties of alloys based on II-S and II-Te chalcogenides

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.
