| 摘 要： | Transparent Ni^2＋-doped magnesium aluminosilicate glass ceramics are prepared. The formation of petalite-type crystallites in the glass ceramics is confirmed by x-ray diffraction. Broadband infrared luminescence centred at around 1235nm with full width at half maximum （FWHM） of about 300nm is observed from the Ni^2＋-doped glass ceramics. The observed infrared emission could be attributed to the ^3T2（F） → ^3A2（F） transition of octahedral Ni^2＋ ions in petalite-type crystallites. Theproduct of the fluorescence lifetime and the stimulated emission cross sections is 1.2 ×10-24 cm^2s.
