中文摘要：

利用滚压振动磨在干法室温条件下，将金属锌制备成为尺度大约在3～5nm的锌量子点，并将纳米锌量子点加热到250℃并与水蒸气进行反应，得到纳米氧化锌与纳米锌的混合物。分别利用能量发射谱仪（EDS）、X射线多晶体衍射仪（XRD）、透射电镜（TEM）测试样品的化学成分和表面形貌。结果表明：锌粉加热到250℃与水蒸气反应得到的产物具有良好的分散性，其特征是棒状和片状结构共存，纳米棒有明显的沿着[0，1，-1，1]晶向的生长趋势。一维ZnO纳米棒材料对应于初始锌纳米晶颗粒，与其他方法中ZnO的生长机制不同，可以认为本文中的ZnO的生长遵从顶端生长机制。

英文摘要：

The miler vibration mill was used to manufacture zinc quantum dots of 3-5 nm in dry mode and at room temperature, then the zinc quantum dots were hydrolyzed with steam under different temperature to obtain hybrid of ZnO and Zn nano-structures. The as-synthesized particles were characterized by XRD, TEM. The results showed that the nano-structure synthesized under 250 ℃ had the highest dispersivity featuring nano-flakes with nano-rods, that grew along the [0,1,-1,1] direction. The ZnO nano-rod grew related with nano-crystalline Zn, and top-up model was proposed for interpreting the nano-rod growth mechanism.
