Mn(II)‐Based Hybrid Halide Ionogel Scintillator Film for Large‐Area and High‐Resolution X‐ray Imaging

cations, Mn─IG exhibits high transparency (nearly 90% transmittance at 550 nm-1100 nm) and homogeneous highly-efficient emission. Taking advantage of its processability, we fabricate an 18 cm × 12 cm scintillation film and successfully realize large-area and high-resolution X-ray imaging. The straightforward and rapid synthesis method on such ionogels paves the way for the low-process-demand preparation of large-area scintillators, and also opens up new routes for the in situ construction of uniform 0D metal halide polymer composites.
