Cr 2 O 3 and NiO are co-doped in transparent forsterite glass ceramics. Absorption, emission spectra and fluorescence lifetime are performed to analyse the luminescence characteristics. Several near-infrared active centres are identified and energy transfer from Cr 3+ and Cr 4+ to Ni 2+ is confirmed. Superbroadband near-infrared luminescence with a full width at half maximum of 700 nm is observed, which covers the whole telecommunication window.
