We have fabricated a triple‐wavelength white‐light organic light‐emitting diode (OLED) by a dual doped technique, providing a BczVBi doped Anthracene layer for blue emission as well as a 4‐Dicyanomethylene‐2‐methyl‐6‐[2‐(2, 3, 6, 7‐tetra‐hydro‐1H, 5H‐benzo[ij]‐quinolizin‐8‐yl)vinyl]‐4H‐pyran (DCM2) doped Alq 3 layer for red emission, combining an undoped Alq 3 layer for green emission. Evidence showed that by adopting the device configuration constituted by a blue emission layer of Anthracene:3%BczVBi, a red emission layer of Alq 3 :0.25%DCM2, and a green emission layer of undoped Alq 3 , a stable and high color purity white‐light OLED could be realized.
