Custom‐Shapable and Reusable Thermoplastic Manganese Halide Scintillation Glass for Curved X‐Ray Imaging

Abstract Luminescent metal halides (MHs), whether in the form of rigid single crystal or flexible polymer‐MH composite, are currently at the forefront of next‐generation scintillator development. However, the stringent conditions required for single crystal growth and the opacity of polymer‐MH composites due to severe light scattering pose challenges for achieving high‐resolution X‐ray imaging of intricate objects with irregular geometries. Herein, a flexible, transparent, and thermoplastic 0D manganese (Mn) halide scintillation glass is reported by using a facile melt‐quenching approach. Through alkylating triethylene diamine (ted) with extended chain length and employing it as the spacer, the coulombic interaction within the 0D manganese halide is greatly attenuated, thus lowering the melting temperature ( T m ) and glass transition temperature ( T g ) necessary for glass formation under a mild condition. The scintillation glass exhibits a high relative light yield of 20784 photons MeV −1 and an impressive spatial resolution of 20.4 lp mm −1 . More importantly, due to the low T g and excellent reusability, one scintillation glass can be custom‐shaped to conform to different matters with various irregular geometries for multiple times, all achieving high‐resolution curved X‐ray imaging. This work opens a new avenue for reusable curved X‐ray imaging through thermoplastic scintillation glasses.
