| 摘 要： | 用Ｒａｍａｎ光谱研究了ＧｅＯ２ ＰｂＯ ＺｎＯ玻璃结构，结果表明，这种三元系统红外玻璃主要以［ＺｎＯ４］单元和含两个非桥氧的［ＧｅＯ４］四面体单元共同构成三维网络。网络中含两个非桥氧的［ＧｅＯ４］四面体数量随ＰｂＯ含量增加而增加，而低含量的ＺｎＯ则能提高网络中［ＧｅＯ４］四面体单元的聚合度。

| Abstract: | Raman spectra have been used to study the structure of GeO 2 glasses with PbO and ZnO additions. The results show that the three-dimensional network within GeO 2 PbO ZnO systems is mainly built up of the tetrahedra units of two non-bridging oxygens and the units. With a increase of lead oxide content the number of the tetrahedra of two non-bridging oxygens increase, while the low zinc oxide content can polymerize the tetrahedra units within the network. |
