Summary: Scintillator-based X-ray imaging has been developed using lanthanide(III)-Cu4I4 heterometallic organic frameworks (Ln-Cu4I4 MOFs) which consist of X-ray absorption centers ([Cu4I4] clusters) and luminescent chromophores (Ln(III) ions). The [Cu4I4] clusters absorb X-ray energy to generate triplet excitons through halide-to-ligand charge transfer (XLCT) and metal-to-ligand charge transfer (MLCT) state. These excitons excite Tb3+ to produce intense X-ray-excited luminescence through energy transfer. Tb-Cu4I4 MOFs exhibit high resistance to humidity and radiation, linear response to X-ray dose rate, and high X-ray relative light yield. X-ray imaging with Tb-Cu4I4 MOFs-based flexible scintillator film shows high spatial resolution.
