Abstract

Nanocomposite systems based on ternary semiconductor compounds ZnS x Se1-x with different compositions (x = 0, 0.3, 0.5, 0.7, 1) in dielectric matrices of nanoporous anodic alumina (AA) are synthesized by ultrahigh vacuum thermal sputtering of a mixture of lead sulfide and selenide powders. The effect of the atomic concentration of solid solutions and structural parameters of the AA template matrix on the crystal structure of synthesized nanocomposites and the local atomic environment of Zn and Se atoms is investigated.
