Researchers use MnBz to develop highly efficient low-cost phosphorescent OLED emitters

Researchers from Korea's Dongguk University developed a new green phosphorescent OLED emitter based on a manganese complex called MnBz. The green MnBz emitter offers high brightness and efficiency and low-cost fabrication without any heavy metals. The green emitter was also used to create a warm-white OLED device.

The new emitter is based on a a zero-dimensional manganese (Mn)-based complexes, produced via solution processing. The green phosphorescent OLED offers a record-breaking quantum efficiency of 11.42% and current efficiency of 56.84 cd A-1
