摘　　要：研究铝(Al)修饰对氧化锌(ZnO)纳米棒的晶体结构、微观形貌和光学性能的影响。以乙酸锌和六亚甲基四胺的混合液为前驱液,采用水热法制备ZnO纳米棒,应用磁控溅射Al的方法修饰ZnO纳米棒,分别使用X射线衍射仪、扫描电子显微镜、紫外-可见分光光度计、拉曼光谱仪和荧光光谱仪对Al修饰前后ZnO纳米棒的表征分析,结果表明:ZnO纳米棒为六方纤锌矿结构、结晶度较高,且沿晶面(002)择优生长;ZnO纳米棒的尺寸均匀、平均直径约为200 nm;修饰后的ZnO纳米棒表面附着一层Al颗粒,Al颗粒能有效增强在波长380 nm^1100 nm范围内的吸收率,同时改善了ZnO纳米棒的光致发光性能。The influences of aluminum(Al)modification on the crystal structure,morphology and optical properties of ZnO nanorods are investigated.The ZnO nanorods are prepared by hydrothermal method using a mixture of zinc acetate and hexamethylenetetramine as precursors.Modification of ZnO nanorods by magnetron sputtering Al.The ZnO nanorods are characterized by X-ray diffractomrter,scanning electron microscope,ultraviolet-visible spectrophotometer,Raman spectrometer and fluorescence spectrometer.The results show that the ZnO nanorods have a hexagonal wurtzite structure and preferential growth along the(002)crystal plane,and high crystallinity.The size distribution of ZnO nanorods is uniform and the average diameter is about 200 nm.The Al-modified ZnO nanorods are coated with a layer of Al particles.Al particles can enhance the absorption rate in the wave range of 380 nm^1100 nm.and the photoluminescence properties of ZnO nanorods are improved.
