Phosphorescent Dopant Materials

About

Phosphorescent dopant materials are often complexes of rare-earth or heavy-metals that emit phosphorescent light, achieving high brightness and color tuning for displays. Unlike fluorescent materials that quickly release energy as light from the "singlet" state, phosphorescent dopants can transition to a longer-lived "triplet" state. They then slowly release this stored energy as light, causing the glow-in-the-dark effect. Phosphorescent organic light-emitting diodes (PhOLEDs) represent the second generation of OLED technology, designed to overcome the efficiency limitations of the first generation fluorescent OLEDs. Typical phosphorescent dopant materials include iridium (Ir), platinum (Pt) and europium (Eu) complexes, often with cyclometalated ligands for highly efficient blue, green and red PhOLEDs. Unlike fluorescent OLEDs, PhOLEDs harvest both singlet and triplet excitons, achieving theoretical 100% internal quantum efficiency.
