| 英文摘要 | Transparent ni2+-doped mgo-al2o3-sio2 glass ceramics without and with ga2o3 were synthetized. the precipitation of spinel nanocrystals, which was identified as solid solutions in the glass ceramics, could be favored by ga2o3 addition and their sizes were about 7.6 nm in diameter. the luminescent intensity of the ni2+-doped glass ceramics was largely enhanced by ga2o3 addition which could mainly be caused by increasing of ni2+ in the octahedral sites and the reduction of the mean frequency of phonon density of states in the spinel nanocrystals of solid solutions. the full width at half maximum (fwhm) of emissions for the glass ceramics with different ga2o3 content was all more than 200 nm. the emission lifetime increased with the ga2o3 content and the longest lifetime is about 250 mu s. the ni2+-doped transparent glass ceramics with ga2o3 addition have potential application as broadband optical amplifier and laser materials.
