Broadband near-infrared emission from transparent Ni2+-doped sodium aluminosilicate glass-ceramics is observed.The broad emission is centred at 1290nm and covers the whole telecommunication wavelength region (1100-1700nm) with full width at half maximum of about 340nm. The observed infrared emission could be attributed to the 3T2(F) → 3A2(F) transition of octahedral Ni2+ ions that occupy high-field sites in nanocrystals. The product of the lifetime and the stimulated emission cross section is 2.15 × 10-24 cm2s. It is suggested that Ni2+-doped sodium aluminosilicate glass ceramics have potential applications in tunable broadband light sources and broadband amplifiers.
