Light-emitting nanocomposites on the basis of ZnS:Cu deposited into porous anodic Al2O3 matrices

Аннотация

A new nanocomposite material, specifically, copper-doped zinc sulfide deposited by vacuum thermal sputtering into anodic aluminum-oxide matrices is proposed for the production of promising electroluminescent light sources. The structure of the chemical bonds is studied, which makes it possible to determine the mechanisms responsible for ultraviolet photoluminescence and electroluminescence of the materials in an electric field at a voltage amplitude of 220 V and frequency of 50 Hz. This will allow the use of the nanocomposite in electroluminescent light sources connected to the standard electrical network.
