Paper 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.
