摘要：

The local environment of Nd-O in a sodium tellurite glass was elucidated as a function of Nd2O3 concentration, from 0.1 to 2.5 mol%, using optical spectroscopy. The Judd-Ofelt (J-O) theory was used to determine the oscillator strength parameters (J-O parameters) of the glasses. According to the J-O parameters, a significant change in the local environment of Nd-O was suggested for the glass containing 1 mol% Nd2O3; the asymmetry of the Nd-O crystal field was shown to be at a maximum and the bond covalency at a minimum. The results were further supported by, a significant shift of the structural hypersensitive band of the glass with 1 mol% Nd2O3, as compared with those of the other glasses.
