摘 要: 利用操作简单的电化学沉积法制备海胆状ZnO/In2O3纳米复合结构。通过扫描电子显微镜(scanning electron microscope, SEM)观察了复合结构的形貌;X射线衍射(X-ray diffraction, XRD)研究了复合结构的晶格结构;光致发光(photoluminescence, PL)谱表征所制备ZnO/In2O3纳米复合结构的光学性质。研究结果表明:这是一种由ZnO纳米线包覆着In2O3核心,呈现出海胆状的ZnO/In2O3纳米复合结构。退火后复合材料结晶性改善的同时,紫外发光增强,并在443 nm观测到与ZnO/In2O3纳米复合结构界面有关的发光峰。制备的ZnO/In2O3纳米海胆状复合结构形貌新颖并且光学性质优异,在新式光电材料应用上前景广阔。

Abstract: Through an electrochemical deposition process, urchin-like ZnO/In2O3 nanocomposite structure was prepared. The surface morphological analysis was carried out by scanning electron microscopy (SEM), the phase and structural analysis was studied by X-ray diffraction (XRD), and the optical property was characterized by photoluminescence (PL). The research results showed that this was a kind of ZnO nanowires coated In2O3 core, which showing an urchin-like ZnO/In2O3 nanocomposite structure. After annealing, the crystallinity of composite materials was improved and ultraviolet emission had enhanced, while the emission peak related to the interface of ZnO/In2O3 nanocomposite structure was observed at 443 nm. The synthesized ZnO/In2O3 nanocomposite structure has a novel morphology and excellent optical property. We believe such urchin-like ZnO/In2O3 nanocomposite structure would have broad application prospects in new photoelectric materials.
