- Abstract
The surface structure and cathodoluminescence (CL) spectra of thin films of YO:Eu obtained by HF ion plasma sputtering were investigated by varying the activator concentration in the range of 1.0-7.5 mole%. The possibility of creating irregular solutions of yttrium and europium oxides and the structural features of the small and large crystallites that form the YO:Eu film were demonstrated on the basis of the shape of the CL spectra at different activator concentrations. The critical distance for interaction between the Eu ions at nodes with C and C point symmetry was estimated, and a mechanism of energy migration between these centers was proposed.
