Abstract

Dynamic structural color based on phase change materials in visible wavelength is of great significance for the development of dynamic color filters and advanced display technology, in which angular effect is still a major challenge. This study proposes a five-layer asymmetric Fabry–Pérot cavity structure based on phase change material (Sb 2 S 3 ) to generate high-purity, low-angular-dependence tunable structural colors. Experimentally achieved red, orange, and yellow colors exhibit high purity (>90%), with minimal spectral shift (
