中文摘要	transparent ni2+-doped beta-ga2o3 glass-ceramics were synthesized. the nanocrystal phase in the glass-ceramics was identified to be beta-ga2o3 and its size was about 3.6 nm. it was confirmed from the absorption spectra that the ligand environment of ni2+ ions changed from the trigonal bi-pyramid fivefold sites in the as-cast glass to the octahedral sites in the glass-ceramics. the broadband infrared emission centering at 1270 nm with full width at half maximum (fwhm) of more than 250 nm was observed. the fluorescence lifetime was about 1.1 mu s at room temperature. the observed infrared emission could be attributed to the t-3 (2g) (f-3) -> (3)a (2g) (f-3) transition of octahedral ni2+ ions. it is suggested that the ni2+-doped transparent beta-ga2o3 glass-ceramics with broad bandwidth and long lifetime have a potential as a broadband amplification medium.
