摘要：

Poly(vinyl pyrrolidone) (PVP)-capped CdS nanoparticles were prepared with CS, as the sulfur source through the hydrothermal process. The obtained nanoparticles were characterized by X-ray diffraction, transmission electron microscopic, ultraviolet-visible and fluorescence spectroscopy. The capped US nanoparticles showed remarkable stability and significantly enhanced luminescence property compared with that of the noncapped ones. We attributed this observation to the surface passivation of the US nanoparticles by the PVP molecules. (C) 2002 Elsevier Science Ltd. All rights reserved.
