Abstract: Spherical or dendritic silver nanoparticles have been synthesized by an electrochemical technique in an aqueous solution containing L-cysteine or citric acid.The silver nanoparticles are characterized by powder X-ray diffraction(XRD), transmission electron microscope(TEM) and UV-Vis absorption spectrum.Atypical XRDpattern of the as prepared silver nanoparticles shows the presence of the diffraction peaks corresponding to the (111), (200), (220), (311) planes.All the peaks in the XRDpattern can be indexed as a fcc structure(JCPDS, No.4-0783).The TEMimage in the presence of Lcysteine shows spherical nanoparticles.But the TEMimage in the presence of citric acid shows dendritic nanoparticles
