以正硅酸乙酯、硼酸、金属钠为前驱体采用溶胶-凝胶法合成含Ag量子点的钠硼硅玻璃.X射线粉末衍射(XRD)分析Ag量子点具有立方相.通过透射电子显微镜(TEM)和高分辨透射电子显微镜(HRTEM)测定量子点的尺寸和分布,结果显示在玻璃中量子点呈规则的球形,并且尺寸在5～13 nm之间.紫外-可见(Uv-vis)吸收光谱仪得到Ag量子点的表面等离子体共振吸收峰大约在406 nm附近；利用飞秒Z-scan技术在800 nm波长处用飞秒钛宝石激光辐照对Ag量子点玻璃的非线性光学性质进行研究,该玻璃的非线性折射率γ、非线性吸收系数β和三阶非线性极化率x(3)分别为-1.72×10-17 m2/W、9.96× 10-11 m/W、1.01×10-11 esu.
