采用溶胶凝胶法以正硅酸乙酯、硼酸、金属钠为前驱体合成了含Sb量子点的钠硼硅玻璃。紫外可见(UV-vis)吸收光谱分析表明量子点玻璃的表面等离子体共振吸收峰在566 nm附近；利用飞秒激光钛宝石Z扫描(Z-scan)技术在 800 nm波长处对玻璃样品的非线性光学性质进行研究，得到了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χ(3)分别为8.59×10-17 m2/W、1.80×10-10 m/W、4.75×10-11 esu；X-射线粉末衍射 (XRD) 分析表明具有斜方六面体晶相结构的Sb量子点成功的掺入到玻璃基体中；通过透射电子显微镜 (TEM) 和高分辨透射电子显微镜 (HRTEM)对量子点的尺寸大小和颗粒分布进行了表征，结果显示Sb量子点在玻璃中呈规则的球形，并且颗粒尺寸在19~25 nm之间。

Antimony (Sb) quantum dots doped in sodium borosilicate glass are synthesized through sol-gel method using tetraethyl orthosilicate(TEOS), boracic acid, and metallic sodium as precursors. Ultraviolet-visible (UV-vis) absorption spectrometer shows that the surface plasma resonance absorption peak of the quantum dots glass is about 566 nm. Nonlinear optical properties of Sb quantum dots doped glass are investigated by using Z-scan technique at the wavelength of 800 nm with femtosecond Tisapphire laser radiation. The values of nonlinear refraction index γ, nonlinear absorption coefficient β and the third-order nonlinear optical susceptibility χ(3) of the glass are estimated to be 8.59×10-17 m2/W, 1.80×10-10 m/W, 4.75×10-11 esu, respectively. X-ray powder diffraction (XRD) analyses reveal that Sb quantum dots with rhombic hexahedron phase are successfully doped in glass substrate. The size and distribution of the quantum dots are measured by transmission electron microscopy (TEM) as well as high-resolution transmission electron microscopy (HRTEM), the results show that spherical shape have formed uniformly in the glass, and the size of these quantum dots rang from 19 to 25 nm.
