• High color rendering index of 86.8 in white device.
• High quantum efficiency of 20.5% in yellowish green device.
• High full width at half maximum of 77 nm in yellowish green device.
High color rendering index phosphorescent white organic light-emitting diodes (PHWOLEDs) were developed using a yellowish green dopant with broad light emission. A yellowish green phosphorescent dopant derived from difluorophenylquinoline ligand was synthesized and showed maximum emission peak at 550 nm and broad light emission with a full width at half maximum of 77 nm in addition to high quantum efficiency of 20.5%. The yellowish green dopant was used in PHWOLEDs to enhance the color rendering index and high color rendering index of 86.8 was obtained with a high quantum efficiency of 15.7%.
