Synthesis and Optical Properties of Au-Ag Alloy Nanoclusters with Controlled Composition

Figure 1

Optical absorption spectra of the bimetallic colloidal samples prepared at different Au/Ag molar ratios, using metal ion solutions of high concentrations (first set of metal ion solutions). The positions of the SPR peaks are plotted against Au mol fraction at the right.
