摘要
采用化学水浴沉积法,在预制晶种层的基底上得到垂直底面生长的有序ZnO纳米棒阵列,再用反应磁控溅射方法,沉积制备ZnO-TiO2复合结构的纳米棒阵列。利用X射线衍射(XRD)和扫描电子显微镜(SEM)对制备得到的样品进行结构和形貌表征,研究了晶种层、水浴生长液浓度和磁控溅射氧氩比对复合纳米阵列的影响。制备得到了具有TiO2分枝的复合纳米棒阵列,并初步探讨了TiO2分枝的形成机理,为制备基于复合纳米棒阵列的器件提供了条件。
The ZnO nanorod arrays were synthesized by chemical bath deposition method on seeds pre-coated substrates.Branched TiO2 were prepared by magnetron sputtering on ZnO nanorod arrays.The morphologies and microstructures of branched ZnO-TiO2 nanorod arrays were characterized with X-ray diffraction(XRD) and field emission scanning electron microscopy(SEM).The formation mechanism of branched ZnO-TiO2 nanorod arrays was also studied.
