摘      要：Organic light-emitting devices(OLEDs) have received widespread attention due to their excellent luminescence performance and *** this work,we demonstrate a novel two-color OLED,in which the forward and reverse units are vertically stacked together using Ag:Mg as an intermediate electrode for charge injection and *** to the extremely thin Ag:Mg film layer has a relatively smooth surface,it plays a critical role in the reverse unit light emission of the ***,it is realized that the device emits green and red light when forward and reverse voltages are applied *** provides a new possibility for future OLEDs lighting and display *** OLEDs were prepared by using such Ag:Mg intermediate electrodes,and a maximum brightness of 451.14 cd/m^(2) and an external quantum efficiency(EQE) of 3.82% were obtained at a small current density.
