Ce3+induced enhancement of Ho3+∼ 2.0 μm emission in Yb3+/Ho3+codoped sodium-zinc-tellurite (TNZ) glass was achieved under 980 nm LD laser excitation. The spectroscopic studies show that the upconversion is remarkably reduced by the presence of Ce3+. The ∼ 2.0 μm fluorescence intensity is nearly triply enhanced, and the energy transfer efficiency from Yb3+to Ho3+is improved from 16.1% to 42.6% by increasing the Ce3+concentration from 0 to 0.8 mol%. The mechanism responsible for the upconversion reduction and ∼ 2.0 μm emission enhancement in Yb3+/Ho3+/Ce3+triply-doped TNZ glass is also discussed. Our results indicate that the Yb3+/Ho3+/Ce3+triply-doped TNZ glass is a promising candidate material for improving the Ho3+2.0 μm fiber laser performance.
