White light emitting device based on a new orange phosphorescent material Ir(DPA-FIpy)3 ((DPA-Flpy)H = (9,9-diethyl-7-pyridinylfluoren-2-yl) diphenylamine) has been fabricated. The white OLED consists of it and a blue phosphorescent material FIrPic (iridum-bis(4,6,-difluorophenyl-pyridinato-N, C2)-picolinate). The threshold voltage is 4.2V, and the brightness reaches 3200 cd/m2 at 10V, 30.3 mA/cm2. The color of the light corresponds to a CIE coordinate of (0.31, 0.41). The highest efficiency of the device can reach 17.8 cd/A or 7 lm/W at 8V, 2mA/cm2.
