英文摘要 | Herein, CsPbBr3 quantum dots (QDs) were successfully synthesized via the supersaturated recrystallization (SR) method by using para-xylene as the anti-solvent. The as-prepared CsPbBr3 QDs exhibited high quantum efficiency (78%) and narrow luminescent peaks with a full width at half maximum of around 21.2 nm. Compared with the commonly-used anti-solvents, para-xylene shows low toxic effect and high freezing point (13.3 degrees C). Therefore, CsPbBr3 QDs can be easily preserved in the refrigerator like an ice-cream for further use. The maximum photoluminescence (PL) emission intensity would reach 90% retention after 60 days' storage in the refrigerator. By using this simple method, the stability of CsPbBr3 QDs has been effectively improved for long-term storage and further application. |
