Preparation of single crystal Ag nanorods arrays by direct electro-deposition

Large-scaled Ag nanorods arrays have been synthesized in lower temperature by direct electro-deposition 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 about 200nm.Moreover,the length of them can be controlled by changing the deposition time.
