摘要： 用Ｘ射线光电子能谱和拉曼光谱方法研究了Ｂｉ２Ｏ３－Ｌｉ２Ｏ系玻璃的结构．Ｘ射线光电子能谱显示Ｂｉ２Ｏ３－Ｌｉ２Ｏ玻璃的Ｏ１ｓ电子结合能非常低，甚至低于碱硅酸盐玻璃中断桥氧的Ｏ１ｓ电子结合能，并且Ｏ１ｓ电子结合能随着氧化锂含量的增加而增加．拉曼光谱显示随着氧化锂含量的增加，位于高波数的拉曼振动带朝着更高的方向移动并且强度增加，而位于低波数的拉曼振动带朝着更低的方向移动并且强度下降；这反映了此系玻璃结构中的铋氧多面体的变形程度随Ｌｉ２Ｏ含量的增加而增加．

Abstract: The structure of the binary (100-x)Bi2O3· xLi2O glass was investigated by Raman
scattering and X-ray photoelectron spectroscopies. Their O1s binding energies of X-ray photoelectron spectroscopy were lower than that of
non-bridging oxygen of alkali silicate glass, and it shifted to higher binding energy with increasing Li2O content. The main Raman
peak shifted to higher wave number and the Raman bands at lower wave numbers disappeared with increasing Li2O content, which was interpreted
that the distortion of network-forming BiOx(x=5 or 6)structural unit was increased with increasing Li2O content.

Key words: glass structure, Raman scattering spectrum, X-ray photoelectron spectrum
