Abstract Organic‐inorganic hybrid cuprous halides (OHCHs) are intriguing candidates for the next generation of scintillators due to their environmental friendliness, simple preparation, and excellent luminescent properties. Herein, a series efficient OHCHs based on inorganic building blocks [Cu 4 Br 6 ] 2− clusters, designated as (TMAA) 2 Cu , (EtTPPh) (MtTBA) (TMAA = N,N,N ‐trimethyltrimethyl‐1‐adamantylammonium; EtTPPh ethyltriphenylphosphonium; MtTBA methyltri‐n‐butylammonium), synthesized via solution method. The three exhibit broadband yellow emissions. Remarkably, 0D shows near‐unity photoluminescence quantum yield, which can be attributed highly localized excitons rigid environment. Impressively, it is demonstrated show scintillation performance with high light yield 46700 photon MeV −1 low detection limit 56.12 nGy air s . Photophysical studies reveal that bright emission in originates from self‐trapped excitons. This work opens an inspirational avenue structure design high‐performance X‐ray scintillators.

Copper-based halides have attracted significant attention due to their unique photophysical properties and diverse coordination configurations. However, enhancing water stability modulating structural transitions in cuprous halide materials remain challenging. In this work, we successfully synthesized three copper(I) halides, (C24H28P)CuBr2 (L1, [C24H28P]+ = hexyltriphenylphosphonium), (C24H28P)2Cu4Br6 (L2), (C24H28P)2Cu4I6 (L3), via solvent volatilization, demonstrating exceptional even after 27 days of submersion. Crystals L1 L2 emit yellow orange light, respectively, under ultraviolet excitation, while L3 emits green light when excited by blue light. A rapid phase transition between occurs stimulated with methanol at room temperature. Further exposure a NaI solution can result substitution Br– ions I– [Cu4Br6]2– form L3. Multimodal anticounterfeiting luminescent labels high-security levels been manufactured based on sequential → transition. Moreover, test paper designed be applied for low-level detection. This work accomplishes the coregulation transformations luminescence switching combining simulations halogen strategies, which not only deepens understanding structure–property relationships but also broadens optical applications these materials.
