以阳离子表面活性剂——十六烷三甲基氯化铵(CTAC)作为添加刺,采用电沉积法在氧化铟锡玻璃基板上制备了ZnO薄膜.并研究了CTAC含量对阴极电流密度、结构、表面形貌、化学态和光学性能的影响.实验发现阴极电流密度和(002)择优取向随CTAC含量的增加而增加.电沉积氧化锌薄膜的表面形貌随CTAC含量的增加由小晶粒变为纳米棒,这表明CTAC在控制表面形貌方面有很重要的作用.X-射线光电子能谱表明Zn2p3/2,Zn2p1/2,O1s的峰位分别为1 020.78 eV、1 046.88 eV和530.8 eV.CTAC对电沉积的影响可能是由于CTAC的吸附作用改变了不同晶面的表面能和生长动力学.此外,研究了ZnO薄膜的光学性能,结果表明当CTAC含量为3.0 mmol/L时,薄膜具有较好的透光性和紫外发射性能.添加不同含量CTAC的ZnO薄膜禁带宽度介于3.27～3.52 eV.
