摘要
Nd3＋ strengthens the Er3＋：2.7-μm emission 104 times in fluorophosphate glass; in addition, it can also decrease its upconversion effects and the 1.5-μm emission accordingly. Cross-relaxation process is the principal transition mechanism in this codoping system. Compared with Er3＋ singly doped glass, J- O parameters along with the Arid, β, TR values of Er3＋ change markedly in Er3＋：Nd3＋ codoped glass because Nd3＋ greatly influences the local environment around Er3＋. Results also show that Nd3＋ has a good 4I13/2 lifetime quenching effect as well as thermal load reduction ability for Er3＋：2.7-μm emission.
