Abstract

The spectral properties of Er³⁺-doped tellurite glasses whose compositions are 40TeO₂-40WO₃-10ZnO-10Na₂O and 40TeO₂-40WO₃-10 PbCl₂-10Na₂O were measured and analyzed by using Judd-Ofelt and McCumber theories. Compared with traditional tellurite glasses, these glasses have more stable thermal properties and the emission spectra and emission cross sections at the 1.53 m band are larger and broader. Based on the measured absorption spectra, the spontaneous transition probabilities, the fluorescence branching ratios and the radiative lifetimes of these glasses were also calculated.
