The optimization of Cu6Y sourced ODS-Cu: Effect of Y2O3 content
Nuclear Materials and Energy, 2023 To refine the dispersive Y2O3 particles and to explore the optimum Y2O3 content, reducing the Y2O3 addition from 1.5 wt% to 0.5 wt% for Cu6Y sourced Cu-Y2O3 was investigated. It was found that reducing the Y2O3 addition had little influence on the number

Electroluminescence of Y2O3:Eu and Y2O3:Sm films
Materials Science-Poland, 2013 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
