Abstract
The calcium bromide-based aluminoborate glass doped with Eu2O3 was prepared at 1473 K in ambient atmosphere. Characteristic electron spin resonance features (g = 2.0, 2.8, 3.4, 4.7, and 6.0) gave the direct evidence for the presence of Eu2+ ions, suggesting that the self-reduction from Eu3+ to Eu2+ ions partially took place during the process of glass formation. Persistent spectral hole burning was observed from 10 to 300 K. The hole burning mechanism as well as the self-reduction for the Eu3+ ions was discussed.
