Korean researchers develop a highly-efficient deep-blue phosphorescent OLED emitter
Researchers from Korea's Pusan National University have developed an efficient deep-blue phosphorescent OLED emitter. The researcher say that their new materials has an EQE of 24% while the color point is CIE (0.149, 0.085).
According to the Korean press, the main achievement in this research was the adjustment of the doping concentration of a novel dopant (mer âIr1) to optimize the balance of electron and holes in the light emitting layer.
