在无催化剂的条件下，以乙酸锌为催化剂，在（100）-Si衬底上快速合成了新颖的花状ZnO结构。所得ZnO产品具有良好的定义花状形貌组成的多层花瓣晶体与锥形功能。高分辨率透射电子显微镜（HRTEM）和相应的选区电子衍射图谱（SAED）表明，这些花瓣晶体本质上是单晶，并且优先沿c轴方向取向。室温光致发光（PL）谱显示，所有样品在376.8nm附近都有明显的紫外发射，而在可见光区有很弱的发射峰，说明花状ZnO结构的单晶花瓣中没有深能级缺陷。对花状ZnO的生长机理进行了讨论。
Novel flowerlike ZnO structures have been rapidly synthesized on (100)-Si substrates via thermolysis of zinc acetate in air ambient without any catalyst. The obtained ZnO products exhibit well-defined flowerlike morphologies consisting of multilayer petal crystals with tapering feature. High-resolution transmission electron microscope (HRTEM) and corresponding selected area electron diffraction pattern (SAED) reveal that these petal crystals are single crystal in nature and preferentially oriented in the c-axis direction. Room-temperature photoluminescence (PL) spectra show that all the samples exhibit prominent UV emissions around 376.8nm and very weak visible emission peaks, which demonstrates that there are few deep-level defects in the single crystal petals of the flowerlike ZnO structures. The growth mechanism of the as-synthesized flowerlike ZnO structures was also discussed.
