| Research Abstract |
Shape and size controlled syntheses of metallic nanocrystals were studied using structural correlation between core and shell.We succeeded in epitaxialgrowth of not only Au@Ag and Au@ Pd core-shell particles having small lattice mismatches below 5 % but also of Au@Cu and Au@Ni ones having large lattice mismatchesabove 10% for the first time. Epitaxial growth mechanisms of each metallic nanocrystal were examined using TEM and TEM-EDS analyses.
