摘要
The CdS nanoparticles synthesized in AOT (bis(2-ethylhexyl) sulfosuccinate, disodium salt) reverse micelle in addition of the electric neutral surface-capping agent of pyridine are characterized by XPS, TEM and the absorption spectra. The values of the first-order hyperpolarizability beta for two kinds of nanoparticles, CdS/AOT(-) and CdS/pyridine/AOT(-), have been experimentally measured in solution by the newly developed hyper-Rayleigh scattering technique. The values of beta are laresr than 10(-27) esu, which are among the largest values reported for solution species. (C) 1998 Elsevier Science Limited. All rights reserved.
