Deep learning–driven chromatic X‐ray imaging based on multicolor halide scintillation film stacks for quantitative densitometry

open access: yesInformation &Functional Materials, EarlyView.
The vapor‐deposited stacking strategy for multicolor halide scintillation films has been developed for chromatic X‐ray imaging, while enabling the systematic curation of a materials genome database. The effectiveness has been demonstrated through segmentation of complex circuit boards and 3D reconstruction of material density distributions.
