Abstract

The results obtained via extended X-ray absorption fine structure and X-ray photoelectron spectroscopy studies of nanocomposite systems based on ZnS:Cu (5 at %) deposited into porous anodic alumina (AA) matrices, a promising material for electroluminescent light sources, are presented. The given results are compared with those corresponding to ZnS:Cu films on a smooth SiO2 surface. To implement the deposition process, we have pioneered the use of s method based on the thermal sputtering of ZnS and Cu powders mixed in a specified mass ratio. For the first time, ZnS:Cu single-crystal nanostructures are demonstrated to be formed in AA matrix pores. In this case, their size is assigned by the pore diameter and they possess better composition stoichiometry and better local ordering of atoms in the immediate environment of zinc.
