Ir(ppy)2(acac) Powder Description

Like Ir(ppy)3, bis[2-(2-pyridinyl-N)phenyl-C](acetylacetonato)iridium(III), or Ir(ppy)2(acac), is one of the most studied OLED materials due to its high quantum yields. When doped into 3,5-Diphenyl-4-(1-naphthyl)-1H-1,2,4-triazole (TAZ), very high external quantum efficiencies of (19.06 ± 1.0%) and luminous power efficiencies of 60±5 lm/W were achieved. This was attributed to the nearly 100% internal phosphorescence efficiency of Ir(ppy)2(acac), coupled with balanced hole and electron injection, and triplet exciton confinement within the light-emitting layer.
