Figure 3.

Au mole ratio of samples synthesized under various residence times at different ratios of Au3+:Ag+. Ratio of Au mole while keeping the temperature at 140°C. Inset (a) is the relationship between Abs. peak and the residence time. Inset (b) and (c) are the plots of the Abs. peak against the Au mole ratio of various Au-Ag alloy NPs. (a): 1:1, (b): 1:5, (c): 1:50.
