英文摘要	Er3+-Doped Germanium Bismuthate Glass was fabricated and characterized. The absorption spectrum and up-conversion spectrum of glass were studied. The Judd-Oflet intensity parameters Omega(t)(t=2, 4, 6), determined based on Judd-Ofelt theory, were found to be Omega(2) = 3. 35 X 10(-20) cm(2), Omega(4) = 1. 34 X 10(-20) cm(2), Omega(6), = 0. 67 X 10(-20) cm(2). Frequency up-conversion of Er3+ doped germanium bismuthate glass has been investigated. The up-conversion mechanisms are discussed under 808 nm and 980 nm excitation. Stimulated emission cross-section of I-4(13/2) -> I-4(15/2) transition was calculated by McCumber theory. Compared to other host glasses, the emission property of Er3+-doped germanium bismuthate glasses has advantage over those of silicate, phosphate and germinate glasses. Er3+-doped germanium bismuth glasses are promising upconversion optical and optic-communication materials.
