在较低温条件下,采用直流电沉积法在AAO模板中成功制备出了大面积生长均匀的单晶Ag蚋米棒阵列.利用扫描电子显微镜(SEM),能谱仪(EDS),透射电子显微镜(TEM),选区电子衍射(SAED)和XRD等分析手段对样品进行形貌表征及成分分析.结果表明,阵列中的Ag纳米棒尺寸均匀,保持着良好的平行度,直径接近200nm,与AAO模板的孔径大小相当,且可以通过控制沉积时间来实现对Ag纳米棒长度的控制.
Large-scaled Ag nanorods arrays have been synthesized in lower temperature by direct electro-deposi-tion in the porous anodic aluminum oxide (AAO) templates. The morphologies, structure of the as-prepared samples have been characterized by scanning electron microscope (SEM),energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM), selected-area electron diffraction(SAED) and X-ray diffraction (XRD). The results showed that all the nanorods of the arrays are nearly parallel and uniform in diameter of a-bout 200nm. Moreover,the length of them can be controlled by changing the deposition time.
