本文研究了Ti离子注入对ZnO纳米棒阵列结构、形貌、光学特性和疏水性的影响.XRD测试表明注入前后ZnO纳米棒均为六方纤锌矿晶体结构.然而,随着对ZnO纳米棒阵列注入剂量的增加,样品沿(002)晶面优先生长的趋势降低,而且当注入剂量达到5×1017/cm2时,甚至出现ZnTiO3( 104)晶面衍射峰,说明了这种物质的存在,而后面的XPS表征也进一步证明了Ti-Zn-O化学键的存在.样品形貌测试表明,离子注入后由于受刻蚀和溅射的作用,不仅使得ZnO纳米棒表面形貌发生了很大的变化,透光率也显著下降.离子注入后ZnO纳米棒表面疏水性受形貌变化的影响也发生了改变,使得其疏水性增强,当Ti离子注入量为1×1017/cm2时ZnO纳米棒表面接触角达到了151.4°.总之,离子注入作为一种较新颖的表明改性方法,通过对ZnO纳米棒阵列改性处理可以明显扩展其潜在应用价值.
