| 摘 要： | 采用CVD技术制备了不同形貌的ZnO纳米棒.并利用XRD、SEM、能谱仪、荧光光谱仪对比研究了其表面结构、成份、相结构及光致发光特性.结果表明,样品形貌随着沉积位置的变化而变化,其生长遵循金属自催化机制.并且表明离子化氧空位的存在有利于ZnO的绿光发射.

| Abstract: | ZnO nanowires of different morphologies have been grown on Si(111) substrates by CVD,The structure and morphology of ZnO nanowires had been studied by X-ray diffraction(XRD) and scanning electron microscope(SEM).the result show that the morphologies vary with the position of substrates regularly.Respectively.The growth mechanism of ZnO nanorods has also been discussed. |
