用Ｒａｍａｎ光谱研究了ＧｅＯ２ＰｂＯＺｎＯ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。
The structure of GeO2PbOZnO glass has been investigated by Raman spectroscopy. The results show that the ternary system infrared glass mainly consists of [ZnO4] units and [GeO4] tetrahedron units containing two non-bridging oxygen atoms to form a three-dimensional network. The number of [GeO4] tetrahedra containing two non-bridging oxygen in the network increases with the increase of PbO content, while the low content of ZnO can increase the degree of polymerization of [GeO4] tetrahedron in the network.
