Abstract
Highly phosphorescent (Ph<sub>4</sub> P)<sub>2</sub> [MnBr<sub>4</sub> ] as a low-cost and environmentally benign emitting material achieves peak current efficiency of 25.4 cd A<sup>-1</sup> and external quantum efficiency (EQE) of 7.2% for nondoped organic light-emitting diodes, and peak current efficiency of 32.0 cd A<sup>-1</sup> and EQE of 9.6% for doped devices with 20% (Ph<sub>4</sub> P)<sub>2</sub> [MnBr<sub>4</sub> ]:27% TCTA:53% 6DCZPPY as a doping emitting layer.
