Emergence of a bismuth-based metal–organic framework as an X-ray scintillator

We report the first study of a bismuth-based metal-organic framework as a scintillator for X-ray detection and imaging. The newly synthesized Bi-TCPE exhibits strong photoluminescence and efficient X-ray-induced radioluminescence, along with excellent stability. Its integration into a flexible polymer matrix enables X-ray imaging, highlighting the great promise of Bi-MOFs as a new class of low-toxicity scintillators.
