摘　　要：采用直接沉淀法制备纳米ZnO单结构粉体和复合结构粉体,利用SEM和PL方法表征分析样品。研究了不同煅烧温度对制备纳米ZnO单结构粉体影响,研究发现较高的煅烧温度可以制备出较高质量低缺陷,均匀性较好的纳米ZnO粉体。通过加入NaOH联合沉淀剂方法控制纳米ZnO复合结构粉体的形成,研究中发现这种较为复杂的ZnO复合结构粉体具有较高的缺陷态密度。The preparation of nano-sized ZnO monomer powders and composite powders with direct precipitation method. The samples characterized by SEM and PL methods. Influence of different calcination temperature on the preparation of nano-sized ZnO powder was studied. The result shows that the homogeneous nano-sized ZnO powder with high quality and less defects can be prepared at the higher calcination temperature. The formation of nano-sized ZnO composite powders can be controlled by adding co-precipitation agent of Na OH. It can be found that this kind of complex ZnO composite powders has a higher density of defect state.
