Paper Abstract

The third order nonlinear optical properties of CdS nanorod film and CdS nanoparticle film were investigated comparatively by using nanosecond laser pulses at 532 nm. It is observed that the values of the nonlinear refractive index n2 (23×10-11 esu), the nonlinear absorption coefficient β (4.4×10-11 m/W) and the effective third order nonlinear susceptibility ) χ(3)eff (1.7×10-11 esu) of CdS nanorod film are larger than CdS nanoparticle film (5.2×10-11 esu, 3.9×10-11 m/W, 1.4×10-11 esu). Experimental results show that the shapes of CdS nanomaterials have effect on their third order nonlinear optical properties. The results were analyzed by use of the Maxwell-Garnett Effective Medium theory (MGT).
