采用恒电位电沉积法，在商用多孔阳极氧化铝（AAO）模板的受限纳米通道内成功制备了具有高纵横比和高密度自支撑Ag纳米线图案的有序Ag纳米线阵列。X射线衍射和选区电子衍射分析表明，合成的样品具有（220）择优取向。透射电子显微镜和扫描电子显微镜研究表明，合成的银纳米线阵列大面积、有序，表面光滑，直径均匀。表面增强拉曼散射（Sers）光谱表明，银纳米线阵列作为基底具有较高的Sers活性。
Ordered Ag nanowire arrays with high aspect ratio and high density self-supporting Ag nanowire patterns were successfully prepared using potentiostatic electrodeposition within the confined nanochannels of a commercial porous anodic aluminium oxide (AAO) template. X-ray diffraction and selected area electron diffraction analysis show that the as-synthesized samples have preferred (220) orientation. Transmission electron microscopy and scanning electron microscopy investigation reveal that large-area and ordered Ag nanowire arrays with smooth surface and uniform diameter were synthesized. Surface-enhanced Raman Scattering (SERS) spectra show that the Ag nanowire arrays as substrates have high SERS activity.
