N2 - 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 Li3O 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-symmetric bridging oxygen Si-O-Al is formed when Al3+ of Al3O3 in the lithium aluminum silicate glass enter into the glass network. The trend of the degradation of UV transmission slows.
