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...

Bilayer Spectral Engineering of Bi 3 + /Te 4 + ‐Doped Cs 2 ZrCl 6 for Human‐Centric Solid‐State Lighting

ABSTRACT Lead‐free vacancy‐ordered double perovskites are promising phosphors for solid‐state lighting, yet achieving white‐light emission with simultaneously high color fidelity, tunable correlated color temperature (CCT), and controllable circadian‐relevant optical response rem...
