The synthesis of MAPbBr3 nanoplatelets with long-term stability and high photoluminescence quantum yield through controlling the synthetic temperature and dilution treatment

Double buffer of MAPbBr3 QDs using a bulk crystal source by the LARP method and MABr modifier for CsPbBr3 perovskite light-emitting diodes

“…The ligand-assisted reprecipitation (LARP) method is simpler than the hot injection method. Additionally, the synthesis method is simple and does not require heating, which can reduce the synthesis time and eliminate the variable temperature [16,17]. Therefore, in this study, we used MAPbBr 3 bulk single crystals as the source material to prepare bulk-crystal source MAPbBr 3 perovskite quantum dots (bc-MAPbBr 3 QDs) by employing the LARP method and to boost the characteristic of the CsPbBr 3 perovskite emission layer.…”
