Nanostructured ZnS : Cu(Mn) Coatings on the Surface of Porous Anodic Alumina for Optical Applications

Abstract

The results of X-ray diffraction, electron microscopy, extended X-ray absorption fine structure (EXAFS) spectroscopy, and X-ray photoelectron spectroscopy studies of nanostructured ZnS : Cu(Mn) coatings obtained by ultrahigh vacuum thermal deposition onto the surface of anodic Al₂O₃ porous matrices are presented. A comparison with data obtained for films on glass substrates is made. Deposition is carried out during the independent evaporation of ZnS powder, metallic Cu, and MnS powder at various temperatures of the evaporation of impurity-ion sources. For the first time, porous nanostructured ZnS : Cu(Mn) films are shown to be formed on the surface of a porous matrix, the structure of which depends on the parameters of the porous structure of the matrices.
