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.
