Highly Luminescent 0D Antimony‐Based Halides for High‐Resolution Flexible X‐Ray Imaging
Flexible scintillator screens with high stability and spatial resolution are essential for X-ray imaging applications. 0D organic–inorganic antimony halides have emerged as promising candidates owing to their superior optical properties and facile synthesis. In this study, high-quality C21H20OPSbCl4 single crystals incorporating dimeric [Sb2Cl8]2− units are synthesized via an evaporation crystallization method. These crystals exhibit intense yellow emission with a photoluminescence quantum yield (PLQY) of 92%. Furthermore, large-area and flexible C21H20OPSbCl4@PMMA scintillator films are fabricated via a template assembly method, achieving a light yield of 26880 photons/MeV, a detection limit of 160 nGyair/s, and a spatial resolution of up to 12.3 lp/mm. These films exhibit excellent mechanical robustness and retain high-resolution X-ray imaging performance even under repeated bending, thereby enabling effective imaging of non-planar objects. These scintillators further demonstrate remarkable stability under light, thermal, and X-ray irradiation. This study highlights the promise of organic–inorganic antimony halides as a platform for developing high-performance flexible scintillators for advanced X-ray detection.
