中文摘要：

以Zn（CH3COO）2.2H2O为源反应物,采用水热合成反应法成功地制备了杯状的氧化锌微晶粉体材料。X射线衍射（XRD）谱的结果表明获得了典型的六方结构晶体。扫描电子显微镜（SEM）照片观测到杯状的氧化锌微晶,并且单个微晶互相结合形成对称结构。实验发现,水热时间影响着晶体的形貌,对其结构变化机制进行了探讨。同时,通过室温光致发光（PL）光谱,对其光学性质进行了研究。

英文摘要：

Cup-like ZnO microcrystal were prepared by hydrothermal method with Zn（CH3COO）2·2H2O as source reactant.The X-ray diffraction spectra show that the typical wurtzite hexagonal structure was obtained.The single cup like ZnO crystals and the symmetric cup like ZnO crystals combined with each other were investigated by SEM photos.The morphology of ZnO crystals were affected by the experimental condition of hydrothermal time,and the formation mechanism were presented.The effect of hydrothermal time modification on the optical property of ZnO crystals were investigated by room photoluminescence（PL） spectra.
