In conventional quantum dot light-emitting diodes (QLEDs), the organic charge transport materials are susceptible to erosion by water and oxygen, which would reduce the efficiency and lifetime of the devices. Herein, we modified the surface of the organic hole transport layer with an ultra-thin Al2O3 layer, which is deposited by using atomic layer deposition technique, to obtain the highly efficie...Show More
In this letter, we report the high-performance quantum dot light-emitting diodes (QLEDs) with a hybrid hole injection layer (HIL) by doping MoOx into poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS). By this method, the Fermi level of HIL increases from 4.9 to 5.3 eV, allowing better energy level matching and more efficient hole injection capability. The resultant devices exhi...Show More
