(A) Energy and FWHM of the bulk plasmon in Au−Ag (a, c) and Au−Pd alloys (b, d) as a function of the Au content, measured by EELS in alloy nanodisks. Reprinted with permission from Ref. [140].

(B) Composition dependence of the surface plasmon resonance (SPR) wavelength for 20 nm spherical Au−Ag alloy nanoparticles with different compositions in water. The R² value corresponds to a third‐order polynomial fit. Inset corresponds to a linear regression of the composition dependence of the SPR wavelength at intermediate gold fractions.
