摘要/Abstract

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.

关键词: CdS纳米棒, 溶胶模板, 控制生长

Abstract: CdS nanorods were synthesized by a soft chemistry method using cadmium nitrate and thioacetamide as starting compounds and DMF as solvent at low temperature(～50℃). The CdS nanorods have diameters of 7～20nm and lengths up to 500nm. Measurements including transmission electron microscopy (TEM), X-Ray diffraction(XRD) and energy-dispersive spec- troscopy(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.

Key words: CdS nanorods, sol templates, controlled growth
