Abstract

In this article, we report on enhanced broadband near-infrared emission in Yb-Bi codoped phosphate glasses. The emission intensity of Yb-Bi codoped glass was ∼32 times larger than that of Bi-doped glass when excited with 980-nm laser diode. The highest 1/e fluorescent lifetime of Yb-Bi codoped glass reached 1650 μs. The dependence of emission intensity and fluorescent lifetime on Yb₂O₃ concentration was investigated. The enhancement of the near-infrared emission is due to energy transfer from Yb³⁺ (²F_5/2-² F_2/2) transition to Bi ions, and the highest energy transfer efficiency reached 50%. Yb-Bi codoped phos, h t lass should be a promising candidate for broadband optical amplification.
