Zinc oxide (ZnO) micro and nanorods were successfully prepared using Pandanus amaryllifolius 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 Pandanus amaryllifolius 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.

露兜树叶提取物在制造致密均匀的氧化锌微棒中的潜力


以露兜树和六亚甲基四胺（HMTA）分别作为稳定剂，采用溶液浸泡法成功制备了氧化锌（ZnO）微米棒和纳米棒。使用相同的前体和不同的稳定剂制备了两种类型的 ZnO 种子层。从紫外-可见吸收光谱中可以看出，所制备的 ZnO 微棒在约 375 nm 处具有吸收，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微棒的六方纤锌矿结构的尖峰。 ZnO 微棒的场发射扫描电子显微镜 (FESEM) 显示平均直径约为 500 nm，而 HMTA 合成的平均直径为 70 nm。一项新发现是露兜树作为绿色稳定剂能够生长具有高结晶度的致密氧化锌微棒结构。结果表明，在 ZnO 种子层制备过程中，来自不同稳定剂的两个样品都极大地改善了 ZnO 的形态和结构特性以及光吸收。这项研究的主要成果将有利于光电应用，例如紫外线 (UV) 传感器。
