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

Abstract Spatial resolution of scintillator is crucial for high‐quality X‐ray imaging, especially in tiny and complicated electronic component. In this work, PrPP 2 MnBr 4 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 PrPP 2 MnBr 4 , thus giving an excellent X‐ray imaging with spatial resolution of 53.5 lp mm −1 , which demonstrates its application on large area detection.
