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,JO parameters along with the Arad,β,τR values of Er3+ change markedly in Er3+:Nd3+ codoped glass because Nd3+ greatly in?uences 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.
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 + Nd3 + codoped glass due to Nd3 + greatly in? uences 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.
