Abstract 0D hybrid Sb(III) halides generally exhibit unique crystal structure and efficient emission. However, achieving white light blue light‐excited near‐infrared (NIR) emission remains an enormous challenge. Herein, a series of (18‐crown‐6@K) 2 SbX 5 (X = Cl, Br) crystals with different Cl/Br rations are synthesized via supramolecular self‐assembly. All compounds show the broadband emission, which stems from self‐trapped excitons in [SbX ] 2− pseudo‐octahedral structure. Particularly, SbCl shows tunable under various excitation wavelengths, ultra‐high luminous efficiency 92.3% is obtained 310 nm excitation. As Br gradually replaces not only bands red‐shift but also facilitate intersystem crossing process singlet to triplet excitons. Thus, independent NIR upon 450 58.2% SbBr crystals. Moreover, high‐performance single‐component light‐emitting diode (WLED) based on LED fabricated, image fusion realized. Finally, combined multiangle imaging WLED irradiation, 3D reconstruction centrifuge tube wrapped capsule successfully demonstrated.

Abstract High‐energy radiation is widely used in medicine, industry, and scientific research. Meanwhile, the detection of environmental ionizing essential to ensure safe use high‐energy radiation. Among detectors, scintillator detectors offer multiple advantages, including simple structure, high sensitivity, excellent adaptability, a favorable performance‐to‐price ratio. However, development high‐performance scintillators that can provide highly sensitive responses radiation, especially α/β particles, remains challenge. In this work, copper cluster ( Cu 4 I (DPPPy) 2 ) with water‐oxygen stability prepared using one‐pot method at room temperature. not only exhibits X‐ray excited luminescence (XEL) under irradiation but also demonstrates scintillation response particles. By integrating photomultiplier tube (PMT) nuclear electronics, an surface contamination monitor successfully developed. This enables excessive particles real‐world environments. The frequency signal intensity significantly surpass those commercial YAP:Ce, BGO, PbWO , anthracene identical conditions, highlighting promising application metal clusters low‐dose detection.
