摘　　要：利用水热法在不同条件下在ITO-PET(tin-doped indium oxide polyethylene terephthalate)上制备氧化锌纳米棒阵列,通过一些定量的参数,如纳米棒的直径、长度和棒密度来表征纳米棒的形貌.通过改变反应条件可以调节上述参数.分别讨论了两个重要条件:反应时间和前驱体浓度.研究表明前驱体浓度对长径比有重要影响.柔性基底上的氧化锌纳米棒作为染料敏化电池的新型光阳极,长径比的改变对柔性电池有重要的影响.可通过调节反应条件来提高柔性染料敏化电池的性能.ZnO nanorod arrays（ZNRs） were prepared on the tin-doped indium oxide polyethylene terephthalate（ITO-PET） by hydrothermal method under different conditions.Morphology of ZNRs was characterized by some quantitative parameters such as the diameter and length of nanorod and the density of rods.All these parameters were adjusted by changing the reaction conditions.Two important reaction conditions including reaction time and precursor concentration are discussed separately.It is demonstrated that the precursor concentration has great influence on the aspect ratio of nanorod.Flexible substrates with ZNRs are used as the novel photoanode of flexible dye-sensitized solar cells（DSCs）.The aspect ratio of nanorod has major influence on the performance of flexible DSCs.The performance of flexible DSCs is improved by controlling the reaction conditions.
