Abstract

CH3NH3PbBr3@CsPbBr3 quantum dots were prepared by epitaxially growing a CsPbBr3 shell on the surface of CH3NH3PbBr3 due to their similar crystal structures. The inorganic CsPbBr3 shell provides enhanced stability for the CH3NH3PbBr3 core. Compared with that of CH3NH3PbBr3, the photoluminescence of CH3NH3PbBr3@CsPbBr3 quantum dots is not only strong, but also stable for months, in addition to having a high quantum yield.
