We report outstanding electroluminescence properties of high-efficiency blue cadmium-free quantum dot light-emitting diodes (QD-LED). External quantum efficiency (EQE) of 14.7% was achieved for QD-LED emitting at 428 nm. Furthermore, we developed high-efficiency and narrow wavelength emission zinc selenide (ZnSe) nanocrystals emitting at 445 nm and achieved QD-LED with an EQE of 10.7%. These new QDs have great potential to be used in next-generation QD-LED display with wide color gamut.
