Abstract Organic–inorganic copper(I) halides (OICHs) have recently attracted great attentions for their unique optoelectronic properties. However, most of them poor stability and narrow excitation in UV region, which seriously hinder applications efficient white light‐emitting diodes (WLEDs). Herein, 0D (C 19 H 18 P) 2 Cu 4 I 6 with super broad‐band (300–500 nm) yellow emission the absolute photoluminescence quantum yield 87.4% is synthesized a quantity gram scale. Specifically, possesses exceptional thermal‐, photo‐, air‐stability, can maintain even if soaked water, ethyl acetate, isopropanol over 30 days. WLEDs remarkable color under various driven currents are fabricated using 450, 400, 365, 310 nm LED chips. The ideal based on single by 450 chip presents high rendering index 86.7, outstanding luminous efficiency 90 lm W −1 . To best knowledge, this highest value that achieved single‐component OICHs blue light chip. This work not only promotes prospect but also significantly broadens application special lighting fields, such as underwater illumination.

Abstract Achieving single‐phase full‐spectrum white light (SFWL) phosphors is a central goal in the optical field because they simplify white‐LEDs assembly and avoid long‐term color instability. Despite many approaches are developed, current SFWL still suffer from chromaticity drift due to inconsistent thermal quenching of multiple emitting centers. Herein, an absolutely structural disorder strategy established develop single‐emitting center‐based phosphor. Precisely controlling flux added induces translation ordered Y 0.75 Ta 0.25 O 1.75 :Bi 3+ disordered 0.785 0.215 1.715 , as directly identified by STEM‐HAADF analyses. Structural enables produce with FWHM 6194 cm −1 (175 nm) employing single activator site, 1352 increase compared cyan‐emitting despite Bi occupies two lattice positions. This SFWL, coupled minimal expansion unit cell inapparent spectral overlap excitation emission bands, ensure zero‐chromaticity shift elevated temperature. A prototype using luminescent layer generates warm without perceptible CIE coordinates under various currents or after extremely continuous operation. work highlights potential designing exceptional stability.
