摘要： An OLED structure including a first organic layer disposed between the anode and the cathode is disclosed. The first organic layer includes a primary phosphorescent emitter and a first host, and where one of the following conditions is true: (1) the first organic layer further includes a secondary emitter; or (2) the OLED further includes a second organic layer disposed between the anode and the cathode, wherein the second organic layer includes a secondary emitter. The phosphorescent emitter has a peak emission wavelength λmax that is ≥600 nm and ≤750 nm, the secondary emitter has a peak emission wavelength λmax that is ≥750 nm, and the first host has a lowest excited state triplet energy T1 that is at least 0.1 eV higher than that of the primary phosphorescent emitter.
