摘    要:采用化学气相沉积法合成了高质量的铟(In)掺杂的氧化锌单晶纳米线。利用扫描电子显微镜、透射电子显微镜和粉末X射线衍射对其形貌与结构进行了表征。结果表明:纳米线的直径约为30nm,粗细均匀,具有六角纤锌矿结构。在纳米线的变温光致发光光谱中,由于In的掺杂,只观察到紫外发射峰,未见可见光发射峰;低温下的紫外发射来自于施主-受主对(donor-acceptor pair,DAP)的跃迁。随着温度的升高,DAP的跃迁逐渐减弱,在高于140K时,紫外发射来自于自由电子到中性受主(free-electron-to-neutral-acceptor,eA0)的跃迁。

关 键 词:铟掺杂氧化锌  纳米线  光致发光  化学气相沉积

Abstract:The single crystalline indium (In)-doped ZnO nanowire (ZNW) with large-scale and good quality was fabricated by a chemical vapor deposition method.The morphology and structure of the ZNW were investigated by scanning electron microscopy,transmission electron microscopy and powder X-ray diffraction.The results show that the diameter of the nanowire is uniform and about 30 nm.The nanowire has the hexagonal wurtzite ZnO phase structure.Only a broad ultraviolet (UV) emission peak was observed in its photolumine...
Keywords:indium-doped zinc oxide  nanowire  photoluminescence  chemical vapor deposition
