Abstract

Outside silver, inside gold: Gold nanoparticles are used as seeds to probe the role of plasmon excitation in the photo-mediated growth of silver nanoprisms. This approach generates novel core-shell nanostructures that contain a spherical (see TEM image, inset shows side view) or triangular-prism gold core with a triangular silver prism shell. The architecture of these particles can be tuned by controlling the excitation wavelength and gold-core diameter. (Figure Presented).
