Manipulating the optical properties of symmetrically branched Au/Pd nanocrystals through interior design

Abstract

Au/Pd octopods with hollow, cubic interiors and O_h symmetry were synthesized for the first time by etching core@shell Pd@Au/Pd octopods to selectively remove their Pd interiors. Integration of multiple architectural features – in this case branching symmetry, composition, and interior design – into one nanostructure provides design strategies to new plasmonic colloids.
