The Yb^(3+)/Er^(3+) co-doped TeO_(2)-WO_(3)-ZnO glasses bubbling with different times were prepared. The infrared (IR) transmission spectra, emission spectra and fluorescence lifetime of Er^(3+) at 1.5μm were measured. The quench effects of OH groups on emission intensity of Er^(3+) at 1.5 μm as well as the relationships between fluorescence decay rate and OH group content were investigated. The constant k_(OH-Er), which represents the strength of the interactions between Er^(3+) ions and OH groups, is approximately 17.0×10^(-20) cm^(4)/s, and is comparable to that for Er^(3+) in Yb^(3+)/Er^(3+) co-doped phosphate glasses.

用BaO等分子取代BaF2的方法研究了氧化物杂质对62ZrF4·8LaE3·32BaF2(mol%)玻璃物理性质的影响.结果表明,杂质氧化物的存在使玻璃在6μm以后的红外透过率下降,在1350cm~(-1)附近产生附加吸收峰,使并玻璃的转变温度、析晶开始温度和粘度升高.杂质氧化物在氟锆酸盐玻璃中引起的附加吸收是由F—Zr—O键在680cm~(-1)处振动的多声子过程所引起.
