Electrohydrodynamically Driven Broadband and Color‐Shifting in Cholesteric Liquid Crystals
Advanced Optical Materials, EarlyView.Ion‐driven electrohydrodynamic effects enable dynamic photonic bandgap modulation in cholesteric liquid crystals under low‐frequency AC driving. By regulating ion‐mediated disturbance of the helical structure, this approach produces two reversible optical responses: rapid color shifting across the visible spectrum and broadband reflection spanning the ...
