Composition dependent spectroscopic behavior of Er{sup 3+} doped telluroborate glasses were prepared and the energy transfer mechanism in Er{sup 3+} ions were investigated for 1.532 µm amplification. The emission cross-section and gain coefficient for {sup 4}I{sub 13/2}→{sup 4}I{sub 15/2} level of Er{sup 3+} ions have been analysed through the Judd-Ofelt and McCumber theory. The excited state decay curves were measured and the effect of TeO{sub 2} on the lifetime for {sup 4}I{sub 13/2}→{sup 4}I{sub 15/2} level of Er{sup 3+} ions has been associated with the various energy transfer mechanism. Further the interaction between Er{sup 3+} and OH{sup −} were investigated and it was confirmed that the OH free radicals in the prepared glasses are dominant quenching center through the non-radiative relaxation that causes the quenching of 1.532 µm amplification. The non-radiative rate through the OH content were calculated and compared with the reported Er{sup 3+} doped glasses.
