An effective method of improving the luminescent properties of rare earth ions in fluoride glasses were *** Pr^3+/Ho^3+co-doped fluorochlorozirconate luminescent glasses were prepared,and the effects of chloride on the spectral properties and structure of the glasses were *** to the results,the glass stability is improved,and the luminescence intensity in the visible range is significantly enhanced with the introduction of *** introducing 7.5 mol% BaCl2,the luminescence intensity reaches the maximum and increases by three times,The mechanism of luminescence enhancement is explained by analyzing the correlation between the composition and the *** chloride ions disperse outside the glass network before the introduction of 7.5 mol% BaCl2 and increased dispersity of Pr^3+and Ho^3+ions in the fluorozirconate glasses.

目的探讨儿童突发性聋10年来的住院病例的疗效及其预后相关因素。方法回顾性分析98例突发性耳聋儿童患者疗效，统计年龄、性别、侧别、就诊时间、听力损失程度、听力曲线类型、耳鸣、眩晕、耳闷等相关因素与预后的关系，并与255例(257耳)成人患者相对比。结果儿童组治疗有效率：低频下降型曲线75.86%,平坦型75.86%,全聋型68.42%,高频下降型23.08%。有序Logistic回归分析结果提示畸变产物耳声发射检查(distortion product otoacoustic emissions, DPOAE)引出、鼓室注射、高频下降型曲线与疗效相关。儿童组总有效率为68.37%,成人组54.86%(P=0.050)。结论儿童突发性聋发病14 d内为黄金治疗时间，低频型及平坦型听力曲线患者疗效优于全聋型及高频下降型。DPOAE引出、鼓室注射是预后的积极因素，高频下降型曲线是危险因素。儿童组疗效优于成人组。

A large-mode-area neodymium-doped silicate photonic bandgap fiber was theoretically designed and experimen- tMly demonstrated. The relative index step between the high-index rods and the background glass was -0.5%, which is the lowest cladding index difference reported on rare-earth-doped all-solid photonic bandgap fibers to our knowledge. An output power of 3.6 W with a slope efficiency of 31- was obtained for a 100-cm-long fiber.
