| 英文摘要 | a series of dy3+-doped and dy3+/tm3+-codoped chalcohalide glasses (72ges(2)center dot 18ga(2)s(3)center dot 10agl) were prepared. the optical properties of the glasses, including judd-ofelt strength parameters, transition probabilities, excited state lifetimes, fluorescence branching ratios and emission cross-sections were calculated based on the absorption and emission spectra. for the dy3+-doped glasses, the emission intensity at 1330 nm increases obviously with increasing of dy3+ doping content from 0.2 to 0.5 wt.%, and the fluorescence lifetimes keep at 40 us. the emission cross-section of the dy3+-doped glass (0.5 wt.%) was calculated to be 4.16 x 10(-20) cm(2). for the dy3+/tm3+-codoped glasses, tm3+ ions can absorb excitation energy and effectively transfer energy to dy3+ ions. the intensified mid-ir emissions were observed obviously, the emission cross-sections for the codoped glasses (0.8 wt.% dy3+ and 0.5 wt.% tm3+ were calculated to be 1.40 x 10(-20) cm(2) at 2900 nm and 1.52 x 10(-20) cm(2) at 4300 nm, respectively.
