摘 要: | 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/m^2, It is also interesting to find that the MQW structure can enhance the colour stability of WOLEDs at different voltages.
