Zinc oxide (ZnO) micro and nanorods were successfully prepared using and hexamethylenetetramine (HMTA) separately as stabilizers using the solution immersion method. Two types of ZnO seed layer were prepared using the same pre-cursor with the different stabilizers. The fabricated ZnO microrods exhibit absorption at ~375 nm as revealed from the UV-Visible absorption spectrum, and this is comparable with ZnO nanorods synthesized using HMTA. X-ray diffraction (XRD) measurement displayed a sharp peak corresponding to the hexagonal wurtzite structure of ZnO microrods. Field emission scanning electron microscopy (FESEM) of ZnO microrods showed average diameter at approximately 500 nm compared to 70 nm of those synthesized from HMTA. A new finding is the ability of as a green stabilizer to grow a dense ZnO microrod structure with high crystallinity. Results reveal that both samples from different stabilizers during the preparation of the ZnO seed layer greatly improved the morphological and structural properties and optical absorption of ZnO. The main outcomes from this study will benefit optoelectronic application, such as in ultraviolet (UV) sensors.
分别使用[具体物质未给出]和六亚甲基四胺（HMTA）作为稳定剂，采用溶液浸渍法成功制备了氧化锌（ZnO）微米棒和纳米棒。使用相同的前驱体和不同的稳定剂制备了两种类型的ZnO籽晶层。紫外可见吸收光谱显示，制备的ZnO微米棒在约375nm处有吸收，这与使用HMTA合成的ZnO纳米棒相当。X射线衍射（XRD）测量显示出对应于ZnO微米棒六方纤锌矿结构的尖锐峰。ZnO微米棒的场发射扫描电子显微镜（FESEM）显示平均直径约为500nm，而由HMTA合成的ZnO纳米棒平均直径为70nm。一个新发现是[具体物质未给出]作为绿色稳定剂能够生长出具有高结晶度的致密ZnO微米棒结构。结果表明，在制备ZnO籽晶层过程中，来自不同稳定剂的两个样品极大地改善了ZnO的形态、结构性能和光吸收。本研究的主要成果将有利于光电子应用，如用于紫外线（UV）传感器。
