| Abstract: | We studied the fluorescence spectrum changes after doping CsPbBr3 with different amounts of Ga3+ by an improved one-pot hot-injection method, and photoluminescence quantum yield (PLQY) reached the highest when the molar ratio of Ga3+ and Pb2+ was 1∶1, which was 47% blue light. We successfully loaded Ga3+-doped perovskite quantum dots onto the cobalt borate crystal material, and found that the fluorescence intensity has no obvious quenching phenomenon for a long time, which enhances the stability of the perovskite quantum. |
