| 摘 要： | 采用热蒸发法在不同的条件下制备出了阵列状和铅笔状的-维纳米ZnO.利用X射线衍射、扫描电子显微镜、场发射测试仪、光致发光谱对ZnO纳米材料的结晶质量、形貌及场发射性能进行了分析.阵列状氧化锌纳米结构c轴择优取向良好,铅笔状氧化锌纳米结构场发射性能良好.两种纳米结构的室温光致发光谱均显示出了强紫外发射峰和弱绿光发射峰.

| Abstract: | Array-like and pencil-like ZnO nanostructures have been successfully synthesized on Si(111)substrates at different insulation conditions by chemical vapor deposition.The topography,structure,field-emission property and optical properties are investigated by field emission scanning electron microscopy,X-ray diffraction,field emission measurements and photoluminescence spectrum,respectively.The array-like ZnO nanostructures are preferentially c-oriented and the field-emission property of the pencil-like ZnO n... |
