Circularly Polarized Structural Color Pigments Tunable Across the Full Visible Spectrum
Advanced Optical Materials, Volume 14, Issue 6, 9 February 2026.By infusing black dye into spherical shells of polymerized cholesteric liquid crystal, blue, green and red omnidirectional retroreflectors of circularly polarized structural color are achieved. They can be laid out on arbitrary surfaces without any need for index matching binder to define graphical information for robots and Augmented Reality devices ...
