    Abstract: An organic light emitting diode (OLED) architecture in which efficient operation is achieved without requiring a blocking layer by locating the recombination zone close to the hole transport side of the emissive layer. Aryl-based hosts and Ir-based dopants with suitable concentrations result in an efficient phosphorescent OLED structure. Previously, blocking layer utilization in phosphorescent OLED architectures was considered essential to avoid exciton and hole leakage from the emissive layer, and thus keep the recombination zone inside the emissive layer to provide high device efficiency and a pure emission spectrum.

    Abstract: A method and apparatus for evaporating a solid organic material by sublimation using an infrared guiding heater which minimizes temperature gradients in the bulk of the organic target. The bulk is heated to a temperature below the sublimation temperature of the target. A localized area of the target is sublimated by the infrared guiding heater while regulating the temperature of the bulk. The vapor is then deposited over, and condensed on, a substrate to form a solid organic layer.

    Abstract: A device is provided, having an anode, a cathode, and a first organic layer disposed between the anode and the cathode. The first organic layer is capable of phosphorescent emissive when a voltage is applied between the anode and the cathode. A second organic layer disposed between the first organic layer and the cathode is also provided. The second organic layer is in direct contact with the first organic layer. The second organic layer may comprise a material having the structure: M maybe selected from the group Ti, Zr, Hf, Nb, Re, Sn and Ge. The substituents R1 through R10 may be selected from the group consisting of alkyl and aryl groups. Each of R1 through R10 may represent no substitution, mono-, di-, or tri- substitution. The second organic layer may comprise a material having a dipole moment less than about 2.0 debyes, such that the device has an unmodified external quantum efficiency of at least about 3% and a lifetime of at least about 1000 hours at an initial photon flux of about 1018 photons / sr-sec. The second organic layer may comprise a metal complex having a plurality of ligands, wherein each ligand makes the same contribution to the highest occupied molecular orbital and the lowest unoccupied molecular orbital of the metal complex. The second organic layer may be in direct contact with the cathode, or there may be a separate organic layer between the second organic layer and the cathode. Other metal complexes having quinolate ligands may be used.
