Resumé

Metallic nanoparticles (NPs) are known for their plasmonic properties allowing them to confine electric fields to nanometric volumes. The strong confinement of the electric field creates very large electric fields in close proximity of the NP, also known as hotspots. The size, shape and material of the NP specifically defines the wavelength, at which light is absorbed due to interaction with the metal electrons, and hence, the properties of the electric field enhancement. One way to increase the absorption of NPs is to create periodic structures. These periodic structures feature so-called Rayleigh anomalies, which occur when the incident light is diffracted in-plane. The diffraction follows the well-known grating equation that depends on the wavelength and lattice period. The diffracted waves can either propagate in the substrate or in the superstrate, thereby increasing the interaction of light with the nanoparticles at the interface. If the lattice NPs comprise a plasmonic resonance at the Rayleigh anomaly wavelength, their absorption increases remarkably, giving rise to so-called lattice plasmons. Generally, periodic nanostructures featuring lattice plasmons are fabricated by electron beam lithography. Our strategy, however, consists of a bottom-up approach for creating periodic structures of gold nanoparticles. We present here a process for capillary-assisted self-assembly of differently shaped NPs into superlattices.
