White organic light-emitting devices with single luminescent layer and their luminescent properties

We presented two kinds of white organic light-emitting devices (OLED) with single luminescent layer including the device with small molecular doped Zn(BTZ)2: ITO/PVK:TPD/Zn(BTZ)2:Rubrene/Al and the device with Blanded LPPP polymer: ITO/Blanded layer /Al has both high brightness and luminescent efficiency,and their CIE coordinates were very close to the equi-energy point. The original studies of the above devices have been made.
