Analysis of the emitting states of an Ir(III) complex with strong blue emission

- [Ir(ppy)3] and [Ir(ptz)3] analysed by low temperature lifetime and MCPL spectroscopy.
- Global fitting of experimental data used to determine splitting of the T1 level.
- Both compounds emit from a non-degenerate three level excited state system.
- [Ir(ppy)3] showed larger T1 excited state splitting than [Ir(ptz)3].
