UV/X‐Ray‐Induced Reduction of Eu 3+ to Eu 2+ in Rare‐Earth‐Based Halide Double Perovskite for Material‐Discriminative X‐Ray Imaging

ABSTRACT Stacked scintillators for x‐ray energy discrimination require at least two emission bands with sufficient spectral separation to avoid signal crosstalk. Rare‐earth‐based double perovskites exhibit narrow‐band luminescence at multiple visible wavelengths, which is advanta...
