Gold nanoparticle faceting and impact on SERS enhancement. (a) SEM images and reconstructions of faceted nanoparticles with different shapes (from top to bottom): cuboctahedron, rhombicuboctahedron, and pentagonal bipyramid. The colors correspond to different lattice planes. (b) Nanoparticle facet size for different average nanoparticle sizes (measured from SEM images). (c) Experimental SERS vs nanoparticle size together with FDTD simulations assuming suitably faceted nanoparticles. The gray dashed line shows the scaling, which is predicted for spherical particles (see SI).
