Abstract: A device is provided. The device includes a first organic light emitting device, which further comprises a first electrode, a second electrode, and an organic emissive layer disposed between the first electrode and the second electrode. The device also includes a first laser device, which further comprises an optical cavity and an organic lasing material disposed within the optical cavity. A focus mechanism is disposed to focus light emitted by the first organic light emitting device onto the first laser device. Preferably, the focus mechanism provides light incident on the first laser device at least 10 times greater, and more preferably at least 100 times greater, in intensity than the light emitted by the first organic light emitting device.

Abstract: Novel combination of materials and device architectures for organic light emitting devices is provided. An organic light emitting device, is provided, having an anode, a cathode, and an emissive layer disposed between the anode and the cathode. The emissive layer includes a host and a phosphorescent emissive dopant having a peak emissive wavelength less than 500 nm, and a radiative phosphorescent lifetime less than 1 microsecond. Preferably, the phosphorescent emissive dopant includes a ligand having a carbazole group.
