| Abstract: | The energy transfer in Er3+: Sm3+ codoped binary TeO2-Li2O (TLO) glass has been studied using 532 nm laser radiation on the basis of fluorescence intensity and the lifetime measurements. It is observed that the trace of erbium ion can be utilized to sensitize the samarium. The mechanism involved in the present case is found to be dipole-dipole. The energy transfer efficiencies, probabilities of energy transfer and the average donor acceptor distance has been evaluated. |
