Abstract

The optical properties of binary and ternary germanate glasses 40.3GeO₂-59.7PbO, 31.3GeO₂-26.8PbO-41.9Bi₂O₃ and 31.5GeO₂-40.4PbO-28.1Bi₂O₃ (wt%) doped with Er³⁺ were investigated. The Judd-Ofelt intensity parameters were calculated and the near-infrared luminescence as well as the upconversion efficiency was analyzed. We observed that the ternary germanate glass containing the highest concentration of Bi₂O₃ presented the largest emission bandwidth for ⁴I_13/2 →⁴I_15/2 transition and the highest infrared-to-visible upconversion efficiency among the samples studied. These results demonstrate that not only the presence of Bi₂O₃ but also the careful choice of its molecular weight plays a key role in optimizing parameters for using germanate glasses for photonics applications.
