| contents | Optical absorption of colloidal dispersion of bimetallic nanoparticles Au/Pd J. F. Sánchez U. Pal Física, Astronomía y Matemáticas Optical absorption Colloidal dispersion Bimetallic nanoparticles Colloidal bimetallic Au/Pd nanoparticles are synthesized by the simultaneous reduction technique from theircorresponding metallic salts in presence of poly(N-vinyl-2-pirrolidone). Depending upon the Au/Pd concentration ratio,bimetallic nanoparticles of different average size are formed. The UV-VIS optical absorption spectra of bimetallicnanoparticles prepared with different Au/Pd molar ratios revealed that the colloidal dispersions prepared by simultaneousreduction are not a simple mixture of monometallic Au and Pd nanoparticles, but the particles are composed of both theAu and Pd metals in the same structural boundary. The same trend is found in their XRD spectra. The average size of thebimetallic particles strongly depended on the molar concentration of Pd in the reaction mixture. The effect of Pdconcentration on the size of bimetallic nanoparticles is studied. 2001 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94201327 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
