中文摘要：

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．

英文摘要：

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.
