摘要：

US nanoparticles were successfully synthesized through a simple and "green" route using starch as a capping agent. The nanoparticles were characterized by means of AFM, X-ray diffraction (XRD), UV-vis absorption and photoluminescence spectroscopy. The X-ray diffraction analysis suggested that the US nanoparticles were of the cubic structure. The AFM gave an average particle size of approximately 10 nm. (C) 2004 Elsevier B.V.
