Ultrahigh X‐Ray Imaging Spatial Resolution Enabled by an 0D Mn(II) Hybrid Scintillator

Spatial resolution of scintillator is crucial for high‐quality X‐ray imaging, especially in tiny and complicated electronic component. In this work, PrPP2MnBr4 single crystal is obtained by dual‐solvent evaporation method, which gives an unprecedented high spatial resolution of 104.3 lp/mm, representingstate of the art among non‐lead metal halides. The study also conducts the preparation of large area scintillation screen (10 cm × 10 cm) by solidifying melted salt PrPP2MnBr4, thus giving an excellent X‐ray imaging with spatial resolution of 53.5 lp mm−1, which demonstrates its application on large area detection. Through the dual‐solvent evaporation method, PrPP2MnBr4 single crystals are obtained, yielding a remarkable spatial resolution of 104.3 lp mm−1, setting a new standard among non‐lead metal halides. Additionally, the preparation of a large area scintillation screen (10 cm × 10 cm) solidified from melted salt PrPP2MnBr4 is explored, showcasing outstanding X‐ray imaging capabilities with a spatial resolution of 53.5 lp mm−1.
