摘要：
Quantum-dots (QDs) usually show pure color and bright emission with a core-shell structure. In particular, II -VI semiconductor QDs applied in light-emitting diodes (LEDs) are highlighted in this review for excellent performance and controllable synthesis. The structures of QD and LED, as well as charge transport materials, have to be designed and optimized for high external quantum efficiency (EQE). As QD-LED efficiencies approach those of Organic LED (OLED), the key challenges facing commercialization are addressed.
