Er3+-codoped TeO2-WO3-La2O3 glasses were prepared. The thermal stability and spectral properties, such as absorption spectra, emission spectra of the glass samples were measured and investigated. Three intensity parameters, electric dipole transition, magnetic dipole transitions were calculated by Judd-Ofelt theory. The relationship of Ω2 and glass composition was analyzed. The emission cross-section of the 4I13/2→4I15/2 transition of Er3+ ions was calculated by McCumber theory. When La2O3 content was up to 5mol%, glass samples showed no onset crystallization temperature (Tx), indicating that they are saitable
for fiber drawing. The results show that TeO2-WO3-La2O3 glass has a good thermal stability and will be a promising host material for 1.5μm broadband amplification.
