Abstract
Core/shell (pseudo type-II) CsPbBr3/ZnS nanocrystals are prepared, showing ∼15 times enhancement in average photoluminescence lifetime compared to CsPbBr3 nanocrystals. The nanocrystal films (without external encapsulation) retain intense luminescence even after being dipped in water for more than 2 days.
