Description

General description

Tris-(2-phenylpyridine) iridium [Ir(ppy)₃] is a heavy metal complex. [Ir(ppy)₃] is the most frequently used precursor molecule for the synthesis of electro-phosphorescent materials, which are then used in organic light emitting diodes (OLEDs). It provides green-color emission and high phosphorescence quantum yield close to unity.
