氧化锌是一种低成本的材料，可以很容易地利用水热合成法加工成不同的形貌。在这项研究中，氧化锌纳米线生长使用六次甲基四胺（HMTA）和氢氧化铵作为碱的水热法。生长时间和温度是不同的，纳米线的结构和光学特征。纳米线的电子显微镜图像显示，氢氧化铵形成尖端，而HMTA形成平坦的尖端。这归因于HMTA的螯合特性。X-射线衍射图显示强c-轴优选的取向所表现出的氢氧化铵生长的纳米线具有较大的可变性的结晶度，而HMTA产生的纳米线，显示随机取向。观察到的光学带隙随溶液温度的两种类型的基地，但表面氧空位缺陷观察到氢氧化铵生长的纳米线的光致发光测量。
ZnO is a low-cost material which can be easily manipulated into different morphologies using hydrothermal synthesis. In this study, ZnO nanowires are grown using hexamethylenetetramine (HMTA) and ammonium hydroxide as bases for the hydrothermal method. The growth time and temperature are varied and the nanowires are characterised structurally and optically. Electron microscopy images of the nanowires show that ammonium hydroxide forms pointed tips whereas HMTA forms flat tips. This is attributed to the chelating properties of HMTA. X-ray diffraction patterns show strongc-axis preferred orientation exhibited by ammonium hydroxide grown nanowires with large variability in crystallinity, whereas HMTA produced nanowires that show random orientation. The optical band gap is observed to decrease with solution temperature for both types of bases, however surface oxygen vacancy defects are observed in photoluminescence measurements of the ammonium hydroxide grown nanowires.
