| Abstract: | A highly efficient bright red electrophosphorescent device using bis(2-methyl-8-quinolinato)4-phenylphenolate aluminum (BAlq) as a hole and exciton blocker is reported. Maximum luminance and external quantum efficiency of the device are 10362 cd/m2 and 7.0% respectively. Commission Internationale de l′Eclairage (CIE) co-ordinates are (0.672, 0.321). In addition, the quantum efficiency is still as high as 4.3% at a current density of 100 mA/cm2. The device can satisfy the requirement of the red in the full color dynamic displays. |
