Green‐Light‐Emitting Diodes based on Tetrabromide Manganese(II) Complex through Solution Process

Highly phosphorescent (Ph4P)2[MnBr4] as a low-cost and environmentally benign emitting material achieves peak current efficiency of 25.4 cd A−1 and external quantum efficiency (EQE) of 7.2% for nondoped organic light-emitting diodes, and peak current efficiency of 32.0 cd A−1 and EQE of 9.6% for doped devices with 20% (Ph4P)2[MnBr4]:27% TCTA:53% 6DCZPPY as a doping emitting layer.
