The average size distribution of Au-Ag alloy NPs. Average size distribution at different Abs. peak, temperature, residence time, and Au3+:Ag+ ratio. Sample A: 432 nm, 140°C, 320 s, 1:10; sample B: 432 nm, 140°C, 120 s, 1:20; sample C: 432 nm, 140°C, 120 s, 1:50; sample D: 509 nm, 120°C, 40 s, 1:10; sample E: 509 nm, 140°C, 15 s, 1:10; and sample F: 509 nm, 160°C, 8 s, 1:10. The black arrow means the A, B, C line uses the top axis. The blue arrow means the line D, E, F uses the bottom axis.
