摘要：

Photo-induced effects in H-2 loaded 1GeO(2):9SiO(2) glass were studied. The intensity of the absorption band at 5.14 eV was reduced with UV illumination. The neutral oxygen vacancy and also the Gr lone pair centers are reduced with the illumination. There is a one-by-one correlation between the reduction of Ge lone pair centers and the generation of Ge-E' center. We propose that a Ge lone pair center reacts with H-2 molecules in glass to generate a Ce-E' center.
