- Abstract
- We have demonstrated high-efficiency and color stable deep-blue organic light emitting diodes (OLED) using 4,4′-Bis(9-ethyl-3-carbazovinylene)-1, 1′ -biphenyl doped in new blue host material as emitting layer. As host change of the doped blue emitter, blue OLED improved efficiency and exhibited color stability. The optimized blue OLED showed the peak external quantum efficiency of 4.72%, luminous efficiency of 5.12 cd/A at 0.08 mA/cm2, and Commission Internationale de I'Eclairage coordinates of (0.15, 0.12) at 1000cd/m2. This result showed higher efficiency of 1.6 times than control device. ©2010 IEEE.
