Abstract Flexible scintillator screens with excellent stability and low detection limits are crucial for X‐ray imaging applications. 0D organic metal halide materials have emerged as a strong contender in the fields, owing to their optical characteristics simple maneuverability. Herein, high‐quality large quantities of C 38 H 36 P 2 Sb Cl 8 single crystals synthesized through solution approach. The prepared dimer‐structure [Sb ] 2− exhibit yellow emission near‐unity high photoluminescence quantum yield (PLQY) 99.8%, possess an exceptional light 41300 photons MeV −1 , limit 45.6 nGy air s . On this basis, large‐size ultra‐flexible utilized is by template assembled method, demonstrating spatial resolution 8.15 lp mm screen can achieve even after multiple bending stretching, which also provide clear non‐planar irregular objects. In addition, shows light, heat, irradiation, water. These results not only expand optoelectronic application field organic‐inorganic hybrid antimony halides but promote rapid development efficient scintillators.

Abstract Photodetectors with weak-light detection capabilities play an indispensable role in various crucial fields such as health monitors, imaging, optical communication, and etc. Nevertheless, the of weak light signals is often severely interfered by multiple factors background light, dark noise circuit noise, making it difficult to accurately capture signals. While traditional technologies like silicon photomultiplier tubes excel sensitivity, their high cost inherent fragility restrict widespread application. Against this background, perovskite materials have rapidly emerged a research focus field photodetection due simple preparation processes exceptional optoelectronic properties. Not only are straightforward cost-effective, but more importantly, they can be flexibly integrated into flexible stretchable substrates. This characteristic significantly compensates for shortcomings rigid electronic devices specific application scenarios, opening up entirely new possibilities technology.
