摘　　要：以硝酸镉与硫代乙酰胺为起始物,采用DMF为溶剂,在低温(～50℃)下通过软化学法合成了CdS纳米棒,其直径为7～20nm,长度达500nm.通过XRD、TEM、SAED以及EDS对纳米棒的结构和成分进行了表征;通过引入乙酰丙酮(AcAc)控制钛酸丁酯水解,形成的溶胶中分子间网络孔道为CdS纳米棒提供了有效的生长模板.CdS nanorods were synthesized by a soft chemistry method using cadmium nitrate and thioacetamide as starting compounds and DMF as solvent at low temperature(similar to50degreesC). The CdS nanorods have diameters of 7similar to20nm and lengths up to 500nm. Measurements including transmission electron microscopy (TEM), X-Ray diffraction (XRD) and energy-dispersive spectroscopy(EDS) were carried out to study the microstructure of the samples. The nanoporous sol templates formed by the controlled hydrolysis and condensation of Ti(OC4H9)(4) in the presence of AcAc provide an effective matrix for the growth of CdS nanorods.
