摘要: A series of CdS nanoparticles with different surfaces were prepared by colloidal chemical method and reverse micelle method. Their second-order nonlinear optical (NLO) properties were experimentally studied in solution by newly developed hyper-Rayleigh scattering (HRS) technique. The results show that "per particle" first-order hyperpolarizability β values are sensitive to the synthetic method and the surface chemical modification.
