A number of materials prospective for optical coatings formation has been developed on the base of some p-, d- and f-metal chalcogenides. The short-wavelength boundary of optical transparency for polycrystalline materials and thin-film coatings lies at 0.4 to 0.8 mum, while long-wavelength one, 22 to 45 mum. The optical transparency region depends on the material composition and shifts towards the long-wavelength region when cation and anion are substituted by heavier analogs. The data obtained can be used to optimize the material composition and conditions of their using.
