摘要： Methods for evaporating (e.g., subliming) a material in the solid state. In one aspect, a mass of the material in the solid state is mixed with a plurality of packing units, wherein each of the packing units comprises an inert material. The structure of each of the packing units, or the structure of an aggregate of the packing units, comprises a plurality of non- smooth features. In one example, Pro-Pak metal meshes can be used, which have a plurality of various types of non-smooth features, including sharp edges, corners, and/or protrusions. These non-smooth features are believed to physically disrupt crust formation during the evaporation process. Also disclosed are other methods for evaporating a material and methods for fabricating an organic thin-film device.

摘要： An organic light emitting device is provided having an emissive layer with an internal interface. The concentration of a second phosphorescent material in a second organic layer is different from the concentration of a first phosphorescent material in a first organic layer, creating the interface. The materials in the first and second organic layers may be the same or different. In addition to this interface within the emissive layer, the device has one or more features designed to mitigate failure mechanisms which may be associated with electrons or excitons passing from the cathode through the emissive layer to damage organic layers on the anode side of the emissive layer. In addition, devices are provided having an interface within the emissive layer as described above, and a lower energy emissive material on at least one side of the interface.

摘要： 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.
