Outside silver, inside gold: Gold nanoparticles are used as seeds to probe the role of plasmon excitation in the photomediated 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.
