Abstract

The tellurite-tungstate glasses containing small amounts of rare-earth ions have been studied experimentally at 77 and 293 K using spectroscopic methods. The photoluminescence (PL) studies reveal the emission of efficient green-yellow light from Tb³⁺ ions and red light from Eu³⁺ ions. The Judd-Ofelt intensity parameters have been derived for Nd³⁺ and Er³⁺ ions from the absorption spectra and they have used to calculate the radiative lifetimes and branching ratios. The quantum efficiency η = 0.95 of the ⁴F_3/2 level of Nd³⁺ ion is higher than the typical value of other tellurite-based glasses. For Er³⁺ ions, PL originating from the ⁴S_3/2,⁴I_11/2 and ⁴I_13/2 levels has been observed and the luminescence decay of the first two levels has been found to be governed by radiative transitions and multiphonon relaxation involving the highest energy of Te-O vibrations.
