摘要:
采用水溶液法，在涂布有氧化锌种晶层的玻璃基板上制备列阵式氧化锌纳米棒。考察不同反应物浓度及退火对氧化锌纳米棒的微观结构、形貌和光学性能的影响。采用X射线衍射(XRD)、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、紫外可见吸收光谱（UV-vis）和光致发光光谱（PL）对氧化锌纳米棒的结构、形貌和光学性能进行表征。结果表明：通过水溶液法制得纤锌矿结构且高定向的六方氧化锌纳米棒，不同摩尔浓度的长晶溶液可以获得不同直径的氧化锌纳米棒。光致发光光谱显示，在接近于430 nm处有一较强的可见光发光峰，其归因于电子从锌间隙缺陷的施体能阶跃迁到价带。
Abstract:
Zinc oxide (ZnO) nanorods were prepared on ZnO-seeds coated glass substrates via aqueous solution method. The effects of different concentrations of the reactant and annealing on the microstructure, morphology and optical properties of ZnO nanorods were investigated. The structure, morphology and optical properties of the ZnO nanorods were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), ultraviolet visible (UV-vis) absorption spectrum and photoluminescence (PL) spectrum, respectively. The results indicate that high vertical hexagonal ZnO nanorods with wurtzite structure and favourable crystallinity can be obtained by the aqueous solution method, that the ZnO nanorods with different diameters can be fabricated in different molar concentrations. Photoluminescence spectra indicate a strong visible emission in nearly 430 nm, which results from electron transit from donor energy level of Zn interstitial to valence band.
