)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379 nm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。
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.
