| 摘 要： | 采用红外光谱和X射线光电子能谱方法研究了锂铝硅酸盐玻璃结构与紫外透过性能的关系.结果表明:紫外透过性能是桥氧键与非桥氧键共同作用决定的.在锂铝硅酸盐玻璃中随着Li2O含量的增加,产生断网结构,非桥氧数量上升,导致紫外透过性能降低.而Al2O3中的Al3+进入玻璃网络形成了Si-O-Al反对称桥氧,减缓透过率的下降趋势.

| Abstract: | The relationship between the ultraviolet(UV) transmission and structure for lithium aluminosilicate glasses is investigated by infrared spectroscopy and X-ray photoelectron spectroscopy.The results show that UV transmission is determined by bridging oxygen bone and non-bridging oxygen bond.In the lithium aluminum silicate glass,with the content of Li2O increasing,the network structure is broken and the account of non-bridging oxygen is raised,which lead to the degradation of UV transmission.However,the anti... |
