Electronic Dimensionality Control of Exciton Localization in Lead‐Free Copper Halide Perovskite Derivatives for Full‐Color, High‐Fidelity, and Circadian‐Tunable White‐Light Emission

ABSTRACT Rare‐earth‐free white light–emitting diodes (WLEDs) require emissive materials that simultaneously deliver high photoluminescence efficiency, spectral complementarity, and environmental stability. Here, an electronic‐dimensionality‐guided design strategy is reported for...
