Figure 2From: In Situ Generation of Two-Dimensional Au–Pt Core–Shell Nanoparticle Assemblies a UV–Visible spectrum for Au–Pt bimetallic NPs generated on ITO surface with varying mole ratio of Au:Pt. Corresponding Au:Pt ratios are shown on the individual spectrum. b UV–Visible spectrum for Au–Pt bimetallic NPs generated on quartz surface with 1:1 mole ratio of Au:PtBack to article page
