| Research Abstract |
Syntheses of various shapes of Au@Ag core-shell particles with FCC structures were studied using microwave-polyol method. We succeeded in the shape selective syntheses of new Au@Ag nanocrystals with {100} Ag shells using DMF as solvent and reductant. New Au@Ag and Au/Ag@Ag particles were also prepared using icosahedral and branched Au cores and their growth mechanisms were clarified on the basis of TEM-EDS and SEM observations.
