【摘要】以硅酸乙酯和钛酸丁酯为原料，采用溶胶－凝胶法制备出了直径为５ｍｍ，最大折射率变化为０．０３的ＴｉＯ２－ＳｉＯ２径向梯度玻璃棒．利用ＴＧ－ＤＴＡ、ＸＲＤ研究了玻璃棒的形成过程更多还原

【Abstract】 The r-GRIN TiO 2-SiO 2 Glass Rod of about 5mm in diameter having a parabolic index profile with the maximum index change of 0.03 has been prepared by the sol-gel process from silicon and titanium alkoxides. The formation process of r-GRIN glass rod has been characterized by TG-DTA and XRD.更多还原
