掺杂CuInS2纳米晶玻璃的三阶非线性光学性质
Third-order Nonlinear Optical Properties of CuInS2 Quantum Dots Doped Glass
摘要
Abstract
CuInS2 nanociystals doped sodium borosilicate glass were prepared by employing both sol-gel and atmosphere control methods. Morphology and microstructure of CuInS2 nanociystals in the glass were characterized 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 nano-crystals 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 y, absorption coefficient β and susceptibility x(3) of the glass are determined to be 8. 57xl0-16 m2/W, 3. 74xl0-8 m/W, and 1.95x10" mVV2, respectively.关键词
