Ir(ppy)3, one of the most successful green-triplet emitters for OLED devices

High quantum yields and thermal stability

Tris(2-phenylpyridine)iridium(III), Ir(ppy)3, is used widely in organic light-emitting diodes (OLEDs) due to its high quantum yields and thermal stability.

Utilising all of its singlet and triplet excitons for the emission, this green light emitting Ir(ppy)3 exhibits a very bright phosphorescence with an internal quantum yield of almost 100% [1, 2, 3]. It is one of the most successful green-triplet emitters in the rapidly developing field of OLED display technology.
