Abstract
We have employed a two-step temperature-controlled strategy to obtain the assembled CsPbBr3/CsPbBr3 Nanodisks. Compared with the conventional CsPbBr3 quantum dots, surface states characterizations and exciton dynamics verify that the interface defect prevents the rapid recombination of excitons and extends the fluorescence lifetime by nearly ten times.
