Correlation of near-unity quantum yields with photogenerated excitons in X-type ligand passivated CsPbBr(3) perovskite quantum dots

We investigated the exciton decay dynamics of CsPbBr(3) perovskite quantum dots (PQDs) through an X-type ligand passivation process. 1-Dodecanethiol (DDT), as an X-type ligand, covers Br vacancies of PQDs and then the photoluminescence quantum yield (PLQY) sharply improved from 76.1% to 99.8%.
