Description
We report on persistent spectral hole burning in the x-ray-irradiated Sm3+-doped fluoroaluminate glasses at room temperature. 0.1SmF3·14.9YF3·10MgF2·20CaF2 10SrF2·10BaF2·35AlF3 (mol%) glass was prepared under an Ar + NF3 (5 vol.%) atmosphere. Absorption and photoluminescence spectra showed that some of the Sm3+ ions in the glass sample were reduced to Sm2+ ions after the x-ray irradiation. The hole was burned in the 7F0-5D0 line of the Sm2+ ions by means of a DCM dye laser. No antihole or increased excitation (absorption) peak was observed around the burned hole. It was concluded that the persistent spectral hole burning was formed by the optically activated recombination of the electrons trapped by the Sm3+ ions with the trapped holes. (author)
