Abstract
The effect of X-ray radiation on the valence state of europium ions in the Y2O3 matrix was studied by EPR. The alternation of the charge of europium ions (Eu3+ → Eu2+ → Eu3+) in the Y2O3 structure was detected. The mechanism of europium reduction to the divalent state under the action of X-ray irradiation is described.
