Binary mixtures of hard colloids self-assemble into a 3D icosahedral quasicrystal under certain conditions. This breakthrough, very recently discovered by the Soft Condensed Matter group in Utrecht (by both simulations and experiments: 10.1038/s41567-020-1003-9), suggests a way forward for the creation of photonic quasicrystals. Due to their non-periodic structure and exotic symmetries, quasicrystals - when created from particles of the right size and refractive index - are very promising candidates for materials that strongly manipulate visible light via band gaps.
