摘要：

In this work, we have investigated the nonlinear optical properties of thermochemically synthesized CdS nanoparticles, The structure and optical property of the nanopartilces were characterized by means of XRD, UV-visible optical spectroscopy, and photoluminescence (PL) and Z-scan technique was used to measure the nonlinear refraction and absorption indexes. X-ray diffraction (XRD) analysis demonstrated hexagonal phase CdS nanoparticles with an average size around 1.8 nm. Band gap of nanocrystals was about 3.2 eV and they showed a broad band emission from 400-750 nm centered at 504 nm. The nonlinear refractive index was about in order of 10-8 (cm2/W), and the nonlinear absorption coefficient was obtained in order of 10-3 (cm/W) with negative sign. The linear absorption coefficient ( was obtained about 2.62 cm-1.
