采用水热合成方法制备了ZnO纳米棒阵列，并对水热过程中ZnO纳米棒阵列形貌的影响因素进行了考察，发现高浓度的前驱液和籽晶层辅助生长都有利于得到直立均匀的ZnO纳米棒阵列。如果不更换反应前驱液，即使延长反应时间，ZnO纳米棒阵列的长度也没有明显的增长。每隔25． h更换新鲜的反应前驱液，ZnO纳米棒阵列的长度会随着反应时间增加而相应的增长。%Preparation of ZnO nanorod arrays by hydrothermal method has been studied .It has been revealed that the high concentration of precursors and the seed layer can facilitate the growth and the vertical and uniform nanorod array can be obtained .The relationship of growth time and the nanorod length was further investigated .The length of the ZnO NRs has no obvious increase without changing of fresh precursors even the growth time was extended .While the length of the ZnO NRs increased linearly with time when the fresh precursors was changed every 2 5. h .
