摘　　要：以Zn(NO3)2和C6H12N4为原料,在玻璃基片上用均匀沉淀法合成ZnO纳米棒。采用正交实验考察了反应溶液浓度、反应时间、反应温度对产品结构的影响,通过扫描电子显微镜(SEM)、X射线衍射(XRD)对产品进行表征,研究了不同制备条件下产品的形貌变化,探讨了ZnO纳米棒的生长机制,确定了最佳工艺参数。研究结果表明,反应溶液浓度0.01mol/L、温度90℃、反应时间3h为最佳反应条件,得到尺度均匀的ZnO纳米棒,最小直径为80nm左右,推测ZnO纳米棒的生长机制为SLS型。ZnO rod arrays were directly grown on glass substrates by homogeneous precipitation usmg an equimolar aqueous solution of Zn（NO3 ）2 and C6 H12 N4. The influence of the solution concentration, reaction time, and reaction temperature was investigated by the orthogonal experiment. The different performance was characterized by scanning electron microscope （SEM） and X-ray diffraction （XRD） at different preparation conditions. The growth mechanism of ZnO nanorods was investigated and the optimum experiment condition was gained. The results show that the concentration is 0. 01mol/L, temperature is 90℃, the reaction time is 3h, and the thickness of ZnO nanorods is uniform and the minimum diameter of ZnO rods is about 80nm under this experiment condition. The growth mechanism of ZnO nanorods is estimated to be SLS-type.
