以乙二胺四乙酸(EDTA)为稳定剂、丁胺(BA)为结构导向模板, 采用水热合成方法制备了尺寸和晶型可控的ZnSe纳米片晶; 利用XRD, TEM, SEM以及紫外-可见漫反射等手段对所得的产物进了表征, 结果表明, 通过改变水热温度和BA用量, 可以实现ZnSe纳米片晶的大小和物相的调控, 并初步分析了其形成过程.

关键词: ZnSe, 纳米片晶, 物相, 形貌

Novel ZnSe nanosheets with tunable size and phase have been facilely synthesized via hydrothermal routes in the presence of neutral butylamine (BA) as structure-directing agent and ethylene diamine tetraacetic acid (EDTA) as stabilizer. The as-synthesized products were characterized via XRD, TEM, SEM and the UV-Visible absorption spectra. The results showed that the hydrothermal temperature and the dosage of BA had an important effect on the size and phase of the products. A possible formation mechanism for the ZnSe nanosheets was also discussed.
