Behavior of Cu-Y2O3 and CuCrZr-Y2O3 composites before and after irradiation [PDF]

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2023
: The Cu-Y2O3 and CuCrZr-Y2O3 materials have been devised as thermal barriers in nuclear fusion reactors. It is expected that in the nuclear environments, the materials should be working on extreme conditions of irradiation.

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

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
