Steady and transient optical properties of CsPbBr3/Pb3(PO4)2 perovskite quantum dots for white light-emitting diodes

Compared with CsPbBr 3 QDs, CsPbBr 3 /Pb 3 (PO 4 ) 2 QDs with a high PLQY of 75.7% show enhanced excitonic optical properties and improved stability. A high-quality WLED device was realized by integrating the green and red CsPbX 3 /Pb 3 (PO 4 ) 2 QDs.
