CdS纳米棒的合成及硫源的影响

Synthesis of CdS nanorods and the effect of sulfur source

溶剂热法合成CdS纳米棒,分别考察了反应介质尤其是硫源对CdS生成的影响.采用X射线衍射(XRD)、扫描电子显微镜(SEM)、紫外-可见吸收光谱(UV-Vis)等对合成的CdS纳米棒的形貌和结构进行分析、表征.结果表明,以乙二胺为溶剂可以合成出CdS纳米棒,不同硫源合成的CdS纳米棒长度明显不同,这可能与硫源的水解释放S2-机理有关.

CdS nanorods were synthesized with solvothermal method,in which the influence of solvent and sulfur source was observed.CdS was characterized by X-ray diffraction（XRD）,Scanning Electron Microscopy（SEM）and UV-Vis absorption spectrum respectively.The results showed that CdS nanorods were synthesized successfully with ethylenediamine as solvents,moreover,lengths of CdS nanorods synthesized by different sulfur sources are obviously different,which was assumed to be related to hydrolytic release S2-mechanism of the sulfur source.
