Flexible copper halide films with outstanding mechanical stability, excellent film uniformity, nearly 100% photo-luminescence quantum yields, and resistance to water and heat were fabricated. Scintillators based on these films exhibit superior scintillation performance with a detection limit as low as 48.6 nGy/s and 17 lp/mm X-ray imaging resolution, representing the highest imaging resolution for powder-based screens.
Flexible copper halide films of 400 cm(2) area were fabricated with outstanding mechanical stability, excellent film uniformity, nearly 100% photo-luminescence quantum yields, and resistance to water and heat. The re-absorptionfree X-ray imaging scintillators engineered based on these films exhibit superior scintillation performance with a detection limit as low as 48.6 nGy/s and 17 lp/mm X-ray imaging resolution, representing the highest imaging resolution for powder-based screens.
