在没有任何催化剂的情况下，采用简单的热蒸发方法在铟锡氧化物衬底上制备了超细ZnO纳米线束，在ZnO纳米柱的六角头部生长了自组织的ZnO纳米线束。所获得的纳米线通常具有8nm的直径，长度延伸至0.25 μ m。该尺寸与ZnO激子玻尔半径（a（B））的数量级相同。室温光致发光测量显示在374 nm（3.32 eV），这是约100 meV的蓝移从体ZnO发射的一个突出的峰。
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 mu m. The size is the same order of magnitude as the ZnO exciton Bohr radius (a(B)). 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.
