摘要：

Germanotellurite glasses in the compositions of TeO2-GeO2-ZnO-Y2O3-Na2O-Er2O3 were prepared by various conditions. The effect of the composition and various drying procedures on the content and the vibration frequency of OH groups was investigated. Among various drying techniques for removing the OH groups, it has been found that bubbling a mixture of dry oxygen gas and carbon tetrachloride shows significant effect on removing OH groups. Also the quenching effect of OH upon the lifetimes of the I-4(11/2) and I-4(13/2) levels of Er3+ in germanotellurite glasses was slight with low Er3+ and OH content.
