Abstract:
We employed a two-step temperature-controlled strategy to obtain assembled CsPbBr3/CsPbBr3 nanodisks. Compared with conventional CsPbBr3 quantum dots, surface-state characterizations and exciton dynamics suggested that the interface defect prevented the rapid recombination of excitons, and extended the fluorescence lifetime by nearly 10-times.
