“…The plasmonic resonances of metal nanoparticles can be compared to theoretically computed spectra to identify relationships between physical and optical properties. There are several theoretical and computational frameworks for modeling electromagnetic fields . The simplest computations use Mie theory, an exact solution to Maxwell's electromagnetic equations for a homogeneous sphere .…”

Colloidal self‐assembly merges the flexibility provided by (wet‐chemical) colloid synthesis and the structural diversity offered by self‐assembly. Using plasmonic nanocrystals as colloidal building blocks, this enables the fabrication of plasmonic superstructures that show optical response superior to the individual colloid properties. In this review, we highlight recent examples of colloidal monolayers featuring coupled plasmonic resonances. Depending on the average inter‐particle distance and the structure of such monolayers, the discussed examples show either near‐field or radiative coupling signatures depending on the critical interference length scale of the localized resonances. In addition, templated assembly is highlighted as a pathway for the preparation of monolayers that show anisotropic optical coupling. The collected works not only reflect the recent state of the art in plasmonic resonance engineering in self‐assembled monolayers, but also point to future directions relevant for their use in nanophotonic applications such as plasmonic lasing.

“…An in-depth appraisal of these is out of the scope of this progress report and for an introduction to the relative merits of each the reader is referred to the excellent review by Parsons et al and references therein. [ 75 ] Regarding the simulation of plasmon resonant particles of arbitrary shape, DDA and BEM are generally the methods of choice. This has been rather dictated by the fact that synthetic approaches to non-spherical particles of gold and silver typically produce highly prismatic, facetted particles.…”

The visual appearance of the artificial world is largely governed by films or composites containing particles with at least one dimension smaller than a micron. Over the past century and a half, the optical properties of such materials have been scrutinized and a broad range of colorant products, based mostly on empirical microstructural improvements, developed. With the advent of advanced synthetic approaches capable of tailoring particle shape, size and composition on the nanoscale, the question of what is the optimum particle for a certain optical property can no longer be answered solely by experimentation. Instead, new and improved computational approaches are required to invert the structure-function relationship. This progress report reviews the development in our understanding of this relationship and indicates recent examples of how theoretical design is taking an ever increasingly important role in the search for enhanced or multifunctional colorants.

“…For example an isolated sphere can be described exactly using Mie theory 1-3 . More complex structures can also be modeled using techniques 4 such as the finite element method (FEM) 5 and finite difference time domain (FDTD) 6 which afford great flexibility in specifying structure geometry.…”

Here we investigate the interaction of metallic nanoparticles which support localized surface plasmon resonances (LSPR). We use dark-field spectroscopy and normal-incidence transmission spectroscopy to investigate the scattering and extinction of metallic nanoparticles on their own and in both ordered and random arrays. We compare experimental results with theory based on the coupled dipole approximation (CDA) and the finite-element method (FEM). CDA is used to demonstrate the ability to indirectly measure the extinction of an individual particle by considering a sparse, disordered, finite array of particles.
