Used as a phosphorescent emitter in organic light-emitting diodes (OLEDs), particularly in red and near-infrared devices. Exhibits high quantum efficiency and good color purity, making it suitable for display technologies and solid-state lighting. Its fluorinated ligands enhance electron transport and improve device stability. Commonly doped into host materials in the emissive layer to achieve efficient energy transfer and reduce concentration quenching. Also explored in sensing and bioimaging applications due to its long emission lifetime and photostability.
