Vázquez Física, Astronomía y Matemáticas Alloy Colloids Nanoparticles Optical properties Colloidal dispersions of Au/Cu nanoparticles are synthesized by the simultaneous reduction technique from theircorresponding metallic ions in presence of poly(N-vinil-2-pirrolidone). The UV-VIS optical absorption spectra of alloynanoparticles prepared with different Au/Cu molar ratio revealed that the colloidal dispersions prepared are not a simplemixture of Cu and Au monometallic nanoparticles, but the particles are composed of both the Au and Cu metals in thesame structural boundary.
