One-dimensional scintillator film with benign grain boundaries for high-resolution and fast x-ray imaging

Science Advances, 2023
Fast and high-resolution x-ray imaging demands scintillator films with negligible afterglow, high scintillation yield, and minimized cross-talk. However, grain boundaries (GBs) are abundant in polycrystalline scintillator film, and, for current inorganic
