We prepare a series of gold-silver alloy nanoparticles with different Au/Ag mole ratio. The UV/Vis absorption spectra of nanoparticle solutions exhibited one surface plasmon resonance absorption band and the surface plasmon absorption band of the gold-silver alloy nanoparticles is blue-shifted with increase the Ag content. Finally, we produced the nanoparticles capping with alkanethiolate and alkanecarboxylate via place-exchange reaction. The nanoparticles have been characterized by ICP-MS, TEM, 13C-NMR, FT-IR, UV-Vis absorption spectroscopy. We suggest that the carboxylate group is coordinated to the Ag ion as a bridging bidentate.
