摘要
采用简单的低温水溶液法,在修饰有ZnO种子膜的玻片上制备出形貌规整、取向性较好的ZnO纳米棒阵列。利用场发射扫描电子显微镜(FE-SEM)、X射线衍射仪(XRD)和荧光测试仪(PL)等对产物的形貌、结构、光致发光特性进行了表征。结果表明,水热生长12 h后,能够得到均匀致密、高度取向的氧化锌纳米棒阵列,每个纳米棒直径大约为150 nm,长度为1.5μm左右。XRD结果显示,ZnO纳米棒的结构为纤锌矿结构,并沿c轴择优生长。荧光测试结果显示,所制备的ZnO纳米棒阵列在383 nm附近有一个强的紫外发射峰,同时在可见光区出现比较弱的蓝绿光发射峰。
Oriented ZnO nanorod arrays have been synthesized on a glass slide coated with ZnO thin films using an aqueous solution method. The morphologies, phase structure, and the photoluminescence （PL） properties of the as-obtained product was characterized by field emission scanning electron microscopy （FE-SEM）, X-ray diffractometer （XRD）, and PL spectrum. The compacted and highly oriented ZnO nanorod arrays were obtained after 12 h of growth. The diameter of a single nanorod was about 150 nm and the length was about 1.5μm. The structure of the product was wurtzitestructure, preferring to grow along the c axis. The PL results indicated that the ZnO nanorod arrays had a sharp UV emission peak at 383 nm, and certain broad visible light emission peaks like blue green emission peak weakly appeared.
