A Non-Doped Phosphorescent Organic Light-Emitting Device with Above 31% External Quantum Efficiency
The demonstrated square‐planar Pt(II)‐complex has reduced triplet‐triplet quenching and therefore a near unity quantum yield in the neat thin film. A non‐doped phosphorescent organic light‐emitting diode (PhOLED) based on this emitter achieves (31.1 ± 0.1)% external quantum efficiency without any ou...

Summary: | The demonstrated square‐planar Pt(II)‐complex has reduced triplet‐triplet quenching and therefore a near unity quantum yield in the neat thin film. A non‐doped phosphorescent organic light‐emitting diode (PhOLED) based on this emitter achieves (31.1 ± 0.1)% external quantum efficiency without any out‐coupling, which shows that a non‐doped PhOLED can be comparable in efficiency to the best doped devices with very complicated device structures. |
