摘要：

Ni2+-Er3+ co-doped glass ceramics containing ZnGa2O4 nanocrystals were fabricated by in situ controlled crystallization method. The adverse energy transfer between Ni2+ and Er3+ could be suppressed in the ZnGa2O4 glass ceramics. And the super-broadband infrared luminescence with full width at half maximum (FWHM) of about 400 nm covering 1.1-1.7 mu m wavelength region was observed in Ni2+-Er3+ co-doped glass ceramics. The two lifetimes of 1NE-GC950 revealed that two luminescence mechanism involved in the luminescence process, Ni2+:T-3(2g) (F-3) -> (3)A(2g) (F-3) and Er3+:I-4(13/2) -> I-4(15/2) respectively. Compared to that in the Ni2+/Er3+ co-doped glass ceramic containing gamma-Ga2O3 and LaF3 nanocrystals, the nanocrystals in the present paper is just only one, ZnGa2O4 nanocrystals, and it could also present super-broadband luminescence.
