Material platform of quantum dots inside single crystal (QDISCs). a Pure MAPbBr3 perovskite crystal (left) and QDISCs (right). QDISC exhibit the color of PbS quantum dots. b Emission from quantum dots under room light captured by a near-infrared camera. c Absorption and photoluminescence spectrum of QDISCs
