描述了一种直接在玻璃基底上制备金属纳米结构阵列的新方法。在涂有锡掺杂氧化铟（ITO）膜的玻璃基板上沉积铝膜。然后将膜阳极氧化以获得多孔氧化铝模板，其孔径范围为5至150 nm，其用作直流电沉积中的模板电极以在纳米孔中制造各种镍纳米线（直径18-180 nm，0.5-2.6 μ m长）。多孔氧化铝膜不仅决定了纳米线的尺寸，而且影响了纳米线的晶向。磁滞回线的测量表明，镍纳米线阵列具有显着的磁各向异性正比于它们的纵横比。垂直于衬底的折射率（H-c）和方形度（M-r/M-s）对于直径为50 nm（1.8 μ m）的Ni纳米线分别为1025 Oe和0.74，对于直径为18 nm（1.2 μ m）的Ni纳米线分别为830 Oe和0.94。
A novel process for fabrication of metal nanostructure arrays directly on glass substrates is described. An aluminum film was sputter-deposited on a glass substrate coated with a tin-doped indium oxide (ITO) film. The films were then anodically oxidized to obtain a porous alumina template, with pore diameters ranging from 5 to 150 nm, which was used as a template-electrode in a direct current electrodeposition to fabricate various nickel nanowires (diameter 18-180 nm, 0.5-2.6 mum long) in the nanopores. The porous alumina films not only define the dimensions of the nanowires but also influence the crystalline orientation. The magnetic hysteresis measurement showed that the Ni nanowire arrays have significant magnetic anisotropy proportional to their aspect ratios. The coercivity (H-c) and the squareness (M-r/M-s) perpendicular to the substrates were 1025 Oe and 0.74 for the Ni nanowires of diameter 50 nm (1.8 mum), and 830 Oe and 0.94 for the Ni nanowires of diameter 18 nm (1.2 mum), respectively.
