The surface structure and cathodoluminescence (CL) spectra of thin films of Y2O3:Eu and Gd2O3:Eu, obtained by high-frequency ion-plasma sputtering, were investigated. By analysis of the form of the cathodoluminescence spectra it was shown that it is possible to create irregular solutions of yttrium and europium oxides and gadolinium and europium oxides in the respective films. It was established that Eu3+ ions replace Gd3+ ions in the Gd2O3 cubic lattice more uniformly than substitution of Y3+ ions by Eu3+ ions in the Y2O3 cubic lattice.
