ZnO纳米棒阵列通过两步化学法制备,首先通过水热法在ITO衬底上制备ZnO晶种,然后把有ZnO晶种的ITO衬底垂直放入以氯化锌和氨水为溶剂的pH值为11的溶液,在85℃恒温条件下生长2h,然后在600 ℃对其进行退火处理,就得到了在ITO衬底上生长的ZnO纳米棒阵列.利用X射线衍射(XRD)、扫描电子显微镜(SEM)、高分辨透射电子显微镜(HRTEM)、紫外可见分光光度计和光致发光谱仪(PL)对样品的晶体结构、形貌和光学性能进行了表征.结果表明制备的高密度棒状ZnO纳米阵列是垂直生长在ITO衬底上,纳米棒的直径大约为150nm,长约1μm,纤锌矿ZnO纳米棒沿着[0002]方向一致生长;ZnO纳米棒阵列在波长为300 ～400 nm处出现了很强的紫外吸收峰;ZnO纳米棒阵列的光致发光光谱在380 nm左右有一个极强的紫外发光峰.研究了衬底放置方式对ZnO晶种形貌和光学性能的影响.最后通过对棒状ZnO纳米阵列形成过程中可能涉及到的化学反应以及形成机理做了简单的分析.
