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 electrical energy into light, resulting in high device efficiency and brightness. Commonly employed in red or near-infrared emitting layers due to its emission profile. Also investigated in photocatalytic reactions and light-driven organic transformations where visible light absorption and long-lived excited states are beneficial. Suitable for use in high-performance, energy-efficient electronic displays and solid-state lighting systems.
