中文摘要：
采用溶胶-凝胶法结合气氛控制制备了CuInS2纳米晶玻璃.利用X射线粉末衍射仪（XRD）和透射电子显微镜（TEM）对CuInS2纳米晶在玻璃中的形貌和微结构进行了表征,并利用飞秒Z扫描技术对该玻璃的三阶非线性光学性质进行了研究.结果表明,在钠硼硅玻璃中形成了尺寸分布为10 nm左右的均一的CuInS2四方晶系纳米晶.该玻璃体现出优良的三阶非线性光学性能,其三阶非线性光学折射率γ、吸收系数β和极化率χ（3）分别为8.57×10-16 m2/W,3.74×10-8 m/W和1.95×10-17 m2/V2.
英文摘要：
CuInS2 nanocrystals doped sodium borosilicate glass were prepared by employing both sol-gel and atmosphere control methods.Morphology and microstructure of CuInS2 nanocrystals in the glass were characte-rized by means of X-ray powder diffraction（XRD） and transmission electron microscope（TEM）.Femtosecond Z-scan technique was employed to study the third-order nonlinear optical properties of the glass.The results show that CuInS2 nanocrystals in tetragonal crystal system form uniformly in the glass,and the size of the nanocrystals is about 10 nm.The results of femtosecond Z-scan technique show that the glass exhibits excellent third-order nonlinear optical properties,and the third-order nonlinear optical refractive index γ,absorption coefficient β and susceptibility χ（3） of the glass are determined to be 8.57×10-16 m2/W,3.74×10-8 m/W,and 1.95×10-17 m2/V2,respectively.
