Hard X-ray Photoemission Spectroscopy was employed to investigate the elemental composition and chemical state of core-shell bimetallic nanoparticles deposited on a solid substrate. A shift in Au 4f_7/2and Ag 3d_5/2binding energies together with the change in surface elemental composition of the nanoparticles suggests that a low-temperature alloying occurs for bimetallic nanoparticles.
