| 英文摘要 | 53.3bio(1.5)-33.3geo(2)-13.4nao(0.5) (cation%) glasses with various tm3+ concentration were prepared by melt-quenching method. these glasses show high density, high refractive index, low phonon energy and good stability against crystallization. absorption spectra of tm3+-doped bismuthate glass were measured to obtain the radiative lifetimes by judd-ofelt theory. the absorption (4.5 x 10(-21) cm(2)) and emission (6.7 x 10(-21) cm(2)) cross-sections were calculated by beer-lambert and mccumber theory. the results show that the tm3+ (f-3(4) -> h-3(6)) in these glasses have high spontaneous radiative transition probabilities and large stimulated emission cross-section. then the fluorescence emission spectra were measured under 808 nm excitation and the maximum emission intensity at 1.8 mu m is obtained at 0.9 mol% tm2o3 in the glasses.
