    AnnotationPhotosensitive powders of cadmium sulphide doped with donors (Cl-, from 0 to 41 mg/g CdS) and acceptors (Cu2+ and Ag+, from 0 to 9 mg/g CdS) were characterized by granulometry, scanning electron microscopy, X-ray diffraction and optical reflectivity spectra. Incorporation of chloride ions caused the increase of band gap energy from 2.27 to 2.38 eV. Polystyrene, poly(methyl methacrylate), poly(N-vinylcarbazole), poly(bisphenol A carbonate) and epoxy resin were used as binders in pastes containing powders. Layers prepared from the pastes were characterized by reflectivity spectra and photonductivity. The layers composed of powders with low doping levels and binders containing bisphenol A group in the chain exhibited the highest photoconductivity.
