The photoluminescence and phase composition of lead sulphide-cadmium sulphide layers obtained by chemical bath deposition

Abstract

The study concerns optical properties and phase composition studies of the layers based on cadmium sulfide-lead sulfide synthesized by the hydro-chemical deposition. The presence of two peaks in the photoluminescence spectra presumably correspond to two different CdS modifications, i.e. the cubic structure of zinc blende and hexagonal structure (wurtzite type). X-ray phase analysis (XRPA) confirmes the presence of both types of crystallites.
