Angle‐Independent Structural Color in Colloidal Amorphous Arrays

Abstract

3-D colloidal amorphous arrays prepared from two different submicron-sized silica particles, exhibit a specific structural color that remains unchanged during the alternation of viewing angle (see figure). The refractive index in amorphous photonic material changes identically in all directions. This isotropic feature of the dielectric distribution leads to wavelength-selective light scattering.
