中文摘要：

利用水热法制备ZnO微米棒。醋酸镁[Mg（CH3COO）2·4H2O]、醋酸锌[Zn（CH3COO）3·2H2O]和六次甲基四胺（C6H12N4）以一定比例配置成反应溶液，把反应溶液加热到90℃，反应时间为24h，能够在硅衬底上生长高质量的ZnO微米棒。用扫描电镜（SEM）和X射线衍射仪对ZnO微米棒的晶体结构和表面形貌进行了分析，结果表明，样品为细长条棒状结构，呈现六方纤锌矿结构，长径比可达10：1，并且在[002]方向择优生长。在样品中并未发现镁离子，它有可能扮演着催化剂的角色。对ZnO微米棒的光毋发光性能进行测量，由PL光谱分析可知，样品在384nm处有一个紫外发光峰，半峰全宽为13nm，紫外发光峰强度比可见发光峰强度大的多，样品的质量较好。

英文摘要：

We configured reaction solution using zinc acetate [ Zn （ CH3 COO） 2· 2H2O ] and methenamine （ C6 H12 N4 ） with a certain percentage, magnesium acetate [ Mg（ CH3 COO）2· 4H2 O ] was added appropriately in the reaction solution. High quality ZnO microrods were prepared on the silicon substrate at 90 ℃ for 24 h by hydrothermal method. Surface morphology and crystal structure of ZnO microrods are analyzed, using scanning electron microscopy （SEM） and X-ray diffraction （XRD）. The results show the sample presents a rod-like shape with a hexagonal cross sections and typical morphology of wurtzite ZnO. The ratio of length and diameter of the ZnO rod is about 10： 1. And the ZnO microrods grow along [ 002 ] direction. Mg ions are not found in the sample, which probably played the role of a catalyst. Photoluminescence （PL） spectrum of ZnO microrods was measured. Room-temperature PL spectrum of the sampie shows an UV luminescence peak located at 384 nm, and the FWHM of the emission peak is only 13 nm, intensity of UV luminescence peak is stronger than that of visible luminescence peak, indicating the high quality of the sample
