Abstract

Abstract : Examples of amorphous photonic structures producing striking structural coloration are easily found in various living organisms such as birds, insects, and sea animals. In article number 1600838, Thomas Yong‐Jin Han and co‐workers show that colloidal assemblies of engineered amorphous photonic materials using pigmentary α‐Fe2 O3 /SiO2 core–shell nanoparticles exhibit non‐iridescent and tunable colors. Dynamic tunability of colloidal assemblies in the visible wavelengths is shown using an electrophoretic deposition process.
