摘要：

The Er-Yb co-doped boro-tellurite glasses with the chemical composition (40-x-y)TeO2+20H(3)BO(3)+15K(2)CO(3)+15SrCO(3)+ +10ZnO+xEr(2)O(3) +yYb(2)O(3) (where x = 1, y = 0, 0.5, 1 and 2 in wt%) have been prepared and their luminescence properties are studied through absorption and luminescence spectral analysis. Judd-Ofelt (JO) intensity parameters are estimated through the optical absorption spectral measurements. Using McCumbar theory the absorption and emission cross-section values for the (4)l(13/2 ->) (4)l(15/2)(1.531 mu m) transition have been calculated. The high value of gain coefficient and gain band width indicates that the prepared glasses are promising materials for broadband optical amplifier applications.
