Abstract
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 β 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 β are larger than 10-27 esu, which are among the largest values reported for solution species.
