In this presentation, we report a flexible X-ray scintillator based on lead halide perovskite quantum dots (PeQDs) hybridized with the organic dye 2,5-diphenyloxazole (PPO) in a polystyrene (PS) matrix to achieve both flexibility and high X-ray detection performance. Energy transfer from PPO to PeQDs enhanced the X-ray-excited emission intensity by 7.66-fold and improved the spatial resolution by approximately 3-fold.
