Calculated UV–Vis spectra (a) and experimental spectra (b) of AuPd NPs as a function of Au composition (Au%). The calculated spectra are recorded by modelling monodisperse 7-nm spherical particles through Mie theory. The complex dielectric function of AuPd is calculated as a function of the molar fraction of Au and Pd components.
