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.
基于荧光强度和寿命测量，利用532 nm激光辐射研究了掺铒离子和钐离子的二元碲酸锂（TLO）玻璃中的能量转移。观察到铒离子的痕量可用于敏化钐离子。发现本案例中涉及的机制为偶极-偶极机制。已评估了能量转移效率、能量转移概率和平均施主-受主距离。
