摘要

Ce ~(3+) induced enhancement of Ho ~(3+) ～ 2.0 μm emission in Yb ~(3+)/Ho ~(3+) 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 Ce ~(3+). The ～ 2.0 μm fluorescence intensity is nearly triply enhanced, and the energy transfer efficiency from Yb ~(3+) to Ho ~(3+) is improved from 16.1% to 42.6% by increasing the Ce ~(3+) concentration from 0 to 0.8 mol%. The mechanism responsible for the upconversion reduction and ～ 2.0 μm emission enhancement in Yb ~(3+)/Ho ~(3+)/Ce ~(3+) triply-doped TNZ glass is also discussed. Our results indicate that the Yb ~(3+)/Ho ~(3+)/Ce ~(3+) triply-doped TNZ glass is a promising candidate material for improving the Ho ~(3+) 2.0 μm fiber laser performance.
