摘要：在通氩气和不同比率氧氨混合气体的条件下，利用射颠磁控溅射法在玻璃衬底上制备铝（A1)掺杂氧化锌（AZ0)薄膜（溅射功率为180W，衬底温度为300℃），并对部分薄膜样品进行400或500℃退火处理。采用X 射线衍射仪（XRD）、原子力显微镜（AFM)和分光光度计对薄膜的结构、表面形貌和光学性能进行测试研究。结果表明，制备的所有薄膜均呈现（002)品面择优生长；与氢气溅射相比，当采用氧氟混合气体溅射时，生长的AZO薄膜晶粒尺寸显著增大：退火处理使2类薄膜的表面粗糙度都明显减小，品粒也有所增大（7%～13%）。其中，在氧氩比为1：2的混合气体中制备的薄膜，经过500℃退火后，品粒尺寸最大（39.4nm），薄膜表面更平整致密，在可见光区平均透过率接近最大（89.3%），

Abstract : Al-doped ZnO (AZO) films were deposited on the ultrasonically cleaned glass substrates by using the radio frequency (RF) magnetron sputtering techniqueat the substrate temperature 30o C and the sputtering power 18o W. The effects of the gas flow ratio of O, to Ar(GFR) and the annealing on the microstructure and the optical properties of AZO filmswere investigatedvia X-ray diffraction, atomic force microscopy, and visible light spectrophotometer. It is found that the AZO films deposited in the mixed gas of Oz and Ar show much larger crystallite size than those deposited in the pure Ar gas, and the surface roughness of the annealed film samples is lower than that of un-annealed ones. As a result, the optical properties of these AZO films are remarkably improved. The AZO films, which were deposited in the GFR1 : 2 mixed gas and annealed at 5oo C , reveal the best comprehensive properties, including thebiggest crystallite size of 39.4 nm, the least roughness of 1.4 nm, and the almost highest visible transmittance of 89.3%.
