Abstract.

The morphologies of Au–Fe alloy nanoparticles with an 11% Fe mean atomic concentration were investigated by means of high-resolution electron microscopy. The icosahedral morphology was very frequently found in the particles that were generated by the vapor condensation method with helium and deposited on an amorphous carbon film. A high fraction of the icosahedral morphology still remained even after the supported particles were annealed at 723 K for 1 h in a vacuum; this suggests the minimum-energy structure for the alloy particles is icosahedral. As for the low production rate of the icosahedral morphology in the pure Au particles produced under the same conditions, the present results indicate that the icosahedral form is stabilized by the addition of Fe atoms into the Au particles.
