Abstract

Electroluminescence of Y2O3:Eu and Y2O3:Sm films, as well as the films coactivated with Eu and Sm, is studied. The electroluminescence spectra are measured. The physical mechanism of electroluminescence is analyzed It is shown that the increase in the heat treatment temperature and the content of doping impurities of the films enhances the intensity of electroluminescence. Additional doping of Y2O3:EuF3 films by the SmF3 impurity, practically does not influence the emission spectrum.
