Ultrathin ZnO nanowire bundles have been synthesized on an indium-tin oxide substrate without any catalyst by using a simple thermal evaporation method, where self-organized ZnO nanowire bundles were grown on the hexagonal heads of ZnO nanocolumns. The nanowires obtained typically have diameters of 8 nm, with lengths extending to 0.25 microm. The size is the same order of magnitude as the ZnO exciton Bohr radius (aB). Room-temperature photoluminescence measurement shows a prominent peak at 374 nm (3.32 eV), which is about 100 meV blue-shifted from the bulk ZnO emission.
通过一种简单的热蒸发方法，在没有任何催化剂的情况下，在氧化铟锡衬底上合成了超薄氧化锌纳米线束，其中自组织的氧化锌纳米线束生长在氧化锌纳米柱的六角形头部。所获得的纳米线直径通常为8纳米，长度延伸至0.25微米。其尺寸与氧化锌激子玻尔半径（aB）处于同一数量级。室温光致发光测量显示在374纳米（3.32电子伏特）处有一个突出的峰，该峰相对于体相氧化锌发射蓝移了约100毫电子伏特。
