Rb 2 CuBr 3 nanocrystals with a high photoluminescence quantum yield (PLQY) of 75% were synthesized and then further mixed with polymethyl methacrylate to form flexible scintillators. The scintillators maintain a high PLQY, even after bending for 2000 cycles and storing in air for 28 days. X-Ray imaging of targeted objects was demonstrated based on the flexible scintillators, which exhibits a detection limit of 63 nGy air s -1 and a spatial resolution of 27.9 lp mm -1 .
