XRD patterns (a) and calculated lattice parameters (b) of as-synthesized AuPd NPs. All the AuPd NPs show a single phase of fcc structure and their diffraction peaks shift from Au standard (PDF#65-2870) to Pd standard (PDF#65-2867) as Au composition (Au%) decreases. The calculated lattice parameters of Au/Pd ratio are linear.
