Features of Formation and Cathodoluminescence of Thin Films of Yttrium and Gadolinium Oxides Activated by Europium

The surface structure and cathodoluminescence (CL) spectra of thin films of Y 2 O 3 :Eu and Gd 2 O 3 :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...

Zusammenfassung:The surface structure and cathodoluminescence (CL) spectra of thin films of Y 2 O 3 :Eu and Gd 2 O 3 :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 Eu 3+ ions replace Gd 3+ ions in the Gd 2 O 3 cubic lattice more uniformly than substitution of Y 3+ ions by Eu 3+ ions in the Y 2 O 3 cubic lattice.
