Abstract

CdS nanocrystals have been prepared by a sonochemical reduction of a mixed solution of CdCl2, Na2S2O3 and (CH3)2CHOH in Ar atmosphere at room temperature. The products were characterized by X-ray diffraction, transmission electron microscopy and X-ray photoelectron spectrum. It was found that the CdS nanocrystal is in ?-CdS structure with an average size of about 5.5 nm in diameter, and the size distribution is very narrow. The chemical mechanism for the formation of CdS nanocrystals is discussed. © 2001 Elsevier Science B.V.
