Persistent spectral hole burning was observed in Eu3+-doped BaO–PbO–P2O5 glasses, and the dependence of hole properties on the glass composition was investigated in relation to the local structure surrounding the Eu3+ ions. The hole was burned on the 7F0 → 5D0 transition of the Eu3+ ions, the depth of which decreased with increasing PbO content, whereas the hole width increased. The hole was burned at 6 K, filled on increase in temperature, and erased above 120 K. Judd–Ofelt parameters and fluorescence line-narrowing spectra indicated that the symmetry of the Eu3+ site increases and the covalency of the Eu–O bond decreases with increasing PbO content.

Al2O3-B2O3-SiO2 glass containing europium ions was prepared by a sol-gel method. The excitation spectrum of the Eu3+ ions in the glass consists of the charge transfer and f-f transition absorptions of the Eu3+ ions. The emission spectrum indicates the coexistence of the Eu2+ and Eu3+ ions. The formation of some reducing agents in the heat-treatment process should be responsible for the reduction from Eu3+ to Eu2+ ions. The fluorescence line-narrowing spectra reveal that there are two different environments for the Eu3+ ions. Persist spectral hole was burned in the excitation of the 5D0-7F0 transition of the Eu3+ ions. We suggested a possible mechanism on the persistent spectral hole burning of the Eu3+ ion in the glass.
