Silver nanoparticles with spheres, rods have been prepared by a pulse sonoelectrochemical technique from an aqueous solution of AgNO₃ in the presence of sodium dodecyl sulfate C₁₂H₂₅NaO ₄S -(SDS). The as-prepared silver nanoparticles are characterized by electron microscopy (TEM, SEM), powder X-ray diffraction (XRD), and UV-vis absorption spectrum. It was found that the concentration of AgNO₃ and SDS affects the shape of the nanoparticles. The crystal size could be varied from 5 nm up to 200 nm by controlling the various electrodeposition and sonic parameters. © 2009 IOP Publishing Ltd.
