Data on the influence of the alloying dopants gadol inium or dysprosium sulfide on the crystal structure of ZnS prepared by self-propagating high-temperature s ynthesis (SHS) are presented. The dopants contribut e to the removal of ZnO impurity from zinc sulfide by a reaction of double exchange resulting in the appearance of lanthanide oxysulfide, Ln2O2S. High-temperature annealing in deep vacuum produc es significant changes in the crystal structure. Products of the reduction of Ln(ІІІ) were reveled by the presence of intense absorption bands in the UV range of the spectrum. Thin-film coatings on glass substrates ha ve the character of a composite consisting of amorphous co mponents and nanoparticles of the cubic modificatio n of ZnS.
