摘要: Ag/Co nanoparticles (NPs) were prepared by a two-step method. First, Ag NPs synthesized "Controlled Current Coulometry" (CCC) electrochemical method using Pt rotating electrode. Then, core-shell through the reduction as core. Both steps accomplished at room temperature. Techniques such patterned X-ray diffraction (XRD) and transmission electron microscopy (TEM) employed for characterization of NPs. Optical properties also investigated UV-Vis spectroscopy. The absorption peak was observed ~400 nm wavelength peaks that detected 425 415 wavelengths reveal formation structure confirmed thermal techniques. We applied "Mie" theory to calculate cross-section band Comparison between results optical those obtained from showed good agreements.
