SEM image (blue colourscale) of an individual, 350 nm long rice-shaped Ag nanoparticle, overlaid by a multiphoton photoemission electron microscopy image (red colourscale) of the same particle. The PEEM image directly shows how, and most importantly where, the rice-shaped nanoantenna enhances the incident laser field.
