Abstract

original image

A scattering of silver: Polyhedral silver nanocrystals display complex and distinct scattering signatures dictated by their shape and size (see picture). The ability to engineer specific plasmon modes should have profound consequences for surface-enhanced Raman spectroscopy, subwavelength optics, and plasmonic transport.
