摘要：

The results of ZnS photodeposition from aqueous ZnS colloid solutions by KrF laser irradiation at 248 nm are given. In this process, the photoexcitation of ZnS colloid particles initiates complex redox processes, resulting in simultaneous ZnS thin film photodeposition and Zn particle precipitation in the bulk of the reaction cell. The zinc-based layers, which were deposited onto quartz substrates were investigated by the XPS technique. The dependence of the ZnS film stoichiometry on the initial colloid concentration and its photoactivity was determined.
