Used as a phosphorescent emitter in organic light-emitting diodes (OLEDs), particularly in display and lighting technologies. Its strong spin-orbit coupling enables efficient conversion of both singlet and triplet excitons, resulting in high internal quantum efficiency. The ligand structure enhances color purity and stability, making it suitable for green to yellow-green emission layers. It is incorporated into the emissive layer of OLED devices through vacuum deposition or solution processing, depending on device architecture. Its thermal and electrochemical stability supports long operational lifetimes in commercial OLED panels.
