Abstract ： We report the white organic-light devices (WOLEDs) employing a multiple quantum-well (MQW) structure, which consist of alternate layers of 4,48-bis(2,28-diphenylvinyl)-1,18-biphenyl (DPVBi) and (DPVBi:rubrene) as the potential barrier and the potential well, respectively. The results demonstrate that the MQW structure can prominently increase the performance of WOLEDs; the double quantum well device exhibits the efficiency up to 5.4 cd/A, and yields a peak luminance of 14206 cd/m2 . It is also interesting to find that the MQW structure can enhance the colour stability of WOLEDs at different voltages.
