| 英文摘要 | two serial dy3+-doped and dy3+, tm3+-codoped (100-x)(0.8ges(2)center dot 0.2ga(2)s(3))center dot xcdi(2) (0 <= x <= 20) chalcohalide glasses were prepared and characterized. by analyzing the absorption and emission measurements of the two serial chalcohalide glasses with the judd-ofelt analysis, we were able to calculate its judd-ofelt strength parameters omega(t) (t = 2, 4, 6), transition probabilities, exited state lifetimes, branching ratios, and emission cross-sections. in the dy3+-doped glasses, increase of cdi2 had positive effect up to 1330nm fluorescence and the emission cross section (sigma(emi)) was estimated to be 4.19 x 10(-20) cm(2) for the 0.2wt% dy3+-doped 64ges(2)center dot 16ga(2)s(3)center dot 20cdi(2) glass. in the dy3+, tm3+-codoped glasses, increase of cdi2 diminished the amount of ethane-like units [s-3(ga)ge-ge(ga)s-3], improved the tm3+: f-3(4) -> dy3+: h-6(11/2) energy transfer efficiency and intensified the mid-infrared emissions. the emission cross sections (sigma(emi)) of the 2900 and 4300nm fluorescences were estimated to be 1.68 x 10(-20) and 1.20 x 10(-20) cm(2) respectively for the 0.2wt% dy3+ and 0.5wt% tm3+ codoped 64ges(2)center dot 16ga(2)s(3)center dot 20cdi(2) glass. these novel chalcohalide glasses are promising candidate materials for fiber-amplifiers and mid-infrared laser devices.
