摘要

Spectral properties of Yb3+ Ni2+ codoped transparent silicate glass ceramics containing Li Ga5 O8 nanocrystals were investigated. The near-infrared emission intensity of Ni2+ was largely increased with Yb3+ codoping due to Yb3+ → Ni2+ energy transfer. The qualitative calculation of the energy transfer constant Cs-a and rate Ps-a showed that the Yb3+ → Ni2+ energy transfer was much greater than in the opposite direction. Yb3+ Ni2+ codoped glass ceramics with 0.75 mol % Yb2 O3 exhibited a near-infrared emission with full width at half maximum of 290 nm and fluorescent lifetime of 920 μs. The glass ceramics are promising for broadband optical amplification.
