Spectroscopic properties of Er 3+ -doped TeO 2 -WO 3 -Bi 2 O 3 (TWB) glass has been investigated. The transition probabilities, excited state lifetimes, and the branching ratios have been predicted for Er 3+ based on the Judd-Ofelt theory. The lifetime of 4 I 11/2 and 4 I 13/2 level were measured fr
The upconversion properties of Er 3รพ doped lead chloride tellurite glasses under 980 nm excitation are investigated. Three intense emission bands centered at 525, 547, and 657 nm corresponding to the transitions 2 H 11=2 ! 4 I 15=2 , 4 S 3=2 ! 4 I 15=2 , and 4 F 9=2 ! 4 I 15=2 , respectively, simult
