| 摘 要： | 利用醋酸锌[Zn(CH3COO)2·2H2O]和六次甲基四胺(C6H12N4)以一定比例配置成反应溶液,通过水热合成法制备了六角锥状ZnO纳米结构。同时,使用了扫描电子显微镜(SEM)、X射线衍射和选区电子衍射(SAED),对样品的形貌与结构进行了分析。结果表明,样品形貌成六角锥状结构,并且在[002]方向择优生长。通过对样品的光学性能测试,由PL光谱分析可知,样品在379nm处有一个较强的紫外发光峰,并且在可见光区域产生了一些较弱的可见光发射峰,表明制备的六角锥状ZnO纳米结构的晶体质量不是很好。除此之外,对六角锥状ZnO的生长机理也进行了讨论。

| Abstract: | Using a hydrothermal method, the single-crystalline ZnO nanowires with a hexagonal cone-shape were synthesized with zinc acetate and hexamethylenetetramine(HMT). The morphology of the hexagonal cone-shaped ZnO was investigated by selected area electron diffraction (SAED) and scanning electron microscopy (SEM) measurements. The photoluminescence (PL) spectrum of the synthesized ZnO nanowires shows a strong ultraviolet (UV) emission at 379 nm and some weak emission peaks at the visible wavelength region. In addition, the formation mechanism of the hexagonal cone-shaped ZnO is discussed. |
