Journal of Applied Spectroscopy Aims and scope

Abstract

The luminescence spectra of Sc2O3, Y2O3, and Y2GeO5 ceramics and thin films exposed to laser and cathode excitation were investigated. The investigation of the properties of longwave luminescence bands in Sc2O3 with maxima at 2.65, 2.35, and 2.05 eV, in Y2O3 with maxima at 2.60, 2.35, and 2.10 eV, and also in Y2GeO5 with maxima at 2.55, 2.25, and 2.00 eV point to the fact that they are caused by radiative recombination of the excited donor‐acceptor pairs Sc3+ (or Y3+)O2−.
