| 摘 要： | 采用水热合成工艺,在不同条件下制备了不同的一维取向ZnO纳米线阵列样品.用X射线衍射仪(XRD)、扫描电镜(SEM)及透射电镜(TEM)对样品的晶体结构和形貌等进行了表征,对样品的场发射特性进行了分析和比较,并用Fowler-Nordheim方程对影响ZnO纳米线场发射的因素进行了研究.结果表明,具有较低生长密度分布、较高的长径比和较尖锐生长端的ZnO纳米线阵列样品具有较好的场发射特性.

| Abstract: | One-dimensional (1D) aligned ZnO nanowire arrays with different morphologies were synthesized by a solution-phase method. The morphology and microstmcture of the products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The field emission property of different ZnO nanowire array samples was compared. The factors that influence the field emission property of the 1D ZnO nanowire arrays were analyzed using the Fowler-Nordheim equation. The results showed that the ZnO nanowire samples with the lower areal density, higher aspect ratio, and thin tips showed much better field emission characteristics. |
