借助表面活性剂辅助溶剂热方法合成了PbS纳米立方微晶,在合成过程中采用正丁醇与水构成溶剂,S2-由硫代乙酰胺在120℃分解提供.X-射线晶体衍射分析(XRD)表明产物属立方晶体,能谱分析(EDS)显示该样品存在Pb与S两种元素,二者比例为1∶1,并对PbS纳米立方微晶的形成机理进行了探讨。
PbS nano-cubic microcrystals were synthesized by surfactant-assisted solvothermal method, n-butanol and water were used as the solvent in the synthesis, and S2- was decomposed by thioacetamide at 120 ° C. X-ray crystallography (XRD ) Showed that the product was cubic crystal. EDS showed that Pb and S were present in the sample, the ratio of the two was 1: 1, and the formation mechanism of PbS nanocubic crystallites was discussed.
