【Abstract】 CdS nanowires have been successfully prepared by a room temperature solid-state reaction of Cd(Ac)2·2.5H2O and Na2S·9H2O in the presence of PEG 400. The obtained samples were characterized by XRD and SEM. It was found that the molecule the PEG played a critical role in the nucleation and growth of CdS.更多还原
