摘　　要：对Au-SiO2复合溶胶制备和性能进行了初步研究。通过正交实验设计,分析了相关因素对硅溶胶性能的影响规律,确定了合适配比的硅溶胶。采用透射电子显微镜(TEM)测试结果,对比分析了Au-SiO2复合溶胶与硅溶胶的差异,对Au-SiO2复合溶胶的研究为Au-SiO2复合薄膜的制备奠定了基础。This article is about a preliminary study on the preparation and properties of Au-SiO2 composite sol, based on the request of hollow-core fiber for ultraviolet laser transmission. Some influence rules of the silica sol are analy- sised by orthogonal experiments,then a advisable formula of silica sol is confirmed. By observing and comparing the difference between Au-Si02 composite sol and silica sol with TEM test, some reasons are presented on the basis of colloid chemistry theory. An important basis for the preparation of Au-SiO2 composite film is established according to the study on Au-SiO2 composite sol.
