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.

Organic–inorganic hybrid copper(I)-based metal halides (OIHCMHs) have emerged as promising alternatives to lead perovskites due their exceptional optical properties. However, the lack of low-energy light-emitting compounds prohibits further applications. Herein, we report an orange–red emissive (C 19 H 18 P) 2 Cu 4 Br 6 with a zero-dimensional structure. The photoluminescence (PL) peak locates at 640 nm PL quantum yield 69.3%, and large Stokes shift is 245 nm. Experimental analyses demonstrate bright broadband light emission derived from synergistic effect metal-to-ligand charge transfer or halide-to-ligand (MLCT/HLCT) excited state cluster-centered (CC) state. Furthermore, can be used phosphor for didoes (LEDs), by adding other blue- cyan-emitting phosphors, white LED high color rendering index over 94 achieved. This work not only demonstrates material design strategies preparing OIHCMHs but also inspires potential low-dimensional in quality

Abstract Exploring structural phase transitions and luminescence mechanisms in zero‐dimensional (0D) metal halides poses significant challenges, that are crucial for unlocking the full potential of tunable optical properties diversifying their functional capabilities. Herein, we have designed two inter‐transformable 0D Cu(I)‐based halides, namely (C 19 H 18 P) 2 CuI 3 Cu 4 I 6 , through distinct synthesis conditions utilizing identical reactants. Their were systematically elucidated by experiments combined with density theory calculations. The bright cyan‐fluorescent high photoluminescence quantum yield (PLQY) 77 % is attributed to self‐trapped exciton emission. Differently, broad yellow‐orange fluorescence displays a remarkable PLQY 83 %. Its mechanism mainly effects metal/halide‐to‐ligand charge transfer cluster‐centered transfer, which stem from strong Cu−Cu bonding interactions (Cu ) 2− clusters.
