摘要：

Silicate glasses, Al2O3.9SiO2, were successfully prepared to incorporate Sm2+ ions using a sol-gel process. The glasses synthesized through hydrolysis of Si(OC2H5)4, Al(OC4H9)3, and SmCl3.6H2O were heated in air, followed by heating in the presence of hydrogen, in which samarium ions were reduced from the trivalent to divalent state. Glasses incorporated with Sm2+ were colorless, transparent, and showed an intense emission with peaks at 683, 700, and 725 nm due to 5D0 --> 7F0,1,2 transitions, respectively, of the Sm2+ ions. Irradiating the glasses with an Ar laser lowered the intensities of emission from Sm2+ ions and did not promote the formation of Sm3+ ions.
