dc.description.abstract | We investigated the optical and electrical properties of molybdenum trioxide-(MoO(3)-) doped (1,1-bis[(di-4-tolylamino) phenyl]cyclohexane) (TAPC) films with different doping concentrations. Based on our results, we have fabricated white organic light emitting diodes (WOLEDs) with multi-emitting layer structures that consist of 1,3-bis(9-carbazolyl) benzene as a host and three phosphorescent dopants: iridium(III) bis[4,6-difluorophenyl]-pyridinato-N, C(2)'] picolinate as a blue dopant, bis(2-phenylbenxothiozolato-N, C(2)') iridium(III) (acetylacetonate) as an orange dopant, and bis(1-phenylisoquinoline) (acetylacetonate) iridium(III) as a red dopant. We improved the power efficiency and decreased driving voltage of WOLEDs by employing a MoO(3)-doped TAPC layer as a hole transport layer. The MoO(3)-doped TAPC layer lowers the driving voltage by about 1.2V and increases the power efficiency from 6.2 lm . W(-1) to 7.9 lm . W(-1) at 1, 000 cd . m(-2), an approximately 27.4% increase. Furthermore, the WOLED has a high color-rendering index, which is about 86 with the Commission Internationale de l'Eclairage 1931 chromatic coordinates of (0.4303, 0.3893) and correlated color temperature of 3008 K. | - |
