Abstract
The fluorescence characteristics of Ce3+:Er3+ codoped fluoride glass are re ported. It is observed that the decay rate of the I-4(11/2) state of Er3+ i ncreased by increasing the Ce3+ concentration. Further, the branching ratio for the transition from the I-4(11/2) state to the I-4(13/2) State of Er3 increased from 0.20 to 0.95 by codoping 6.0 mol% Ce3+ into Er3+-doped ZBLA N-H fluoride glass. As a result, the 1.55 mu m fluorescence quantum yield h as been significantly improved.
