摘要：

Multicomponent telluride-tungstate glasses containing Nd3+ and Er3+ ions were studied experimentally at 77 and 293 K using spectroscopic methods. The Judd-Ofelt intensity parameters were derived from the absorption spectra and used to calculate the radiative lifetimes and branching ratios. The quantum efficiency eta = 0.95 of the F-4(3/2) level of Nd3+ ion is higher than the typical value of other tellurite-based glasses. For low concentration of Er3+ ions, the luminescence decay of the S-4(3/2) and I-4(11/2) levels is governed by radiative transitions and multiphonon relaxation involving the Te-O highest energy vibrations.
