Abstract
The OLED device using 6% of Os(fptz)2(PPh2Me) 2 as the dopant emitter in a CBP host and BPAPF as hole transporting material shows an external quantum efficiency of 15.3% and luminous efficiency of 21.3 cd A-1, power efficiency of 6.3 lm W-1 at 20 mA cm-2. An even higher external quantum efficiency of ∼20% was achieved at a low current density of ∼1 mA cm-2.
