Time-dependent UV–Vis spectra of Ag-Au alloy nanoparticles (NPs) prepared from PSSMA-Ag NPs:HAuCl4 at molar ratios a 1:2 and b 1:0.125. c UV–Vis absorption spectra of Ag-Au alloy NPs at different Ag mole fractions. d Plot of the wavelength corresponding to the maximum absorbance against the Ag mole fraction for Ag-Au alloy NPs obtained by varying the mole fractions of HAuCl4 while keeping the concentration of Ag NPs constant (CPSSMA-Ag NPs = 0.14 mM). The solid line is a linear fit of the absorption maximum to the increasing Ag mole fraction. The squares correspond to the experimental data
