    摘要： The present invention relates to an organic light emitting device structure having an organic light emitting device (OLED) over a substrate, where the OLED has, for example, an anode, a hole transporting layer (HTL), a first electron transporting layer (ETL) that is doped with a phosphorescent material, a second electron transporting layer (ETL), and a cathode. The OLEDs of the present invention are directed, in particular, to devices that include an emissive layer comprised of an electron transporting host material having a triplet excited state energy level that is higher than the emissive triplet excited state energy level of the phosphorescent dopant material.

    摘要： An optoelectronic device and a method of fabricating a photosensitive optoelectronic device includes depositing a first organic semiconductor material on a first electrode to form a continuous first layer; depositing a layer of a second organic semiconductor material on the first layer to form a discontinuous second layer, portions of the first layer remaining exposed; and depositing the first organic semiconductor material on the second layer to form a discontinuous third layer, portions of at least the second layer remaining exposed. The depositing of the first and second organic semiconductor materials are alternated a number of times until a final layer of the second organic material is added to form a continuous layer. A second electrode is deposited over this final layer. One of the first electrode and the second electrode is transparent, and the first organic semiconductor material is one or more donor-type materials or one or more acceptor-type materials relative to second organic semiconductor material, which is one or more materials of the other material type.

    摘要： A patterned roller, and a method of making the patterned roller, is provided. A patterned roller may be made by first forming a first mold having a negative pattern by etching pits in a flat mold surface with an etching process. Then, a second mold is formed having a positive pattern, by pouring a first curable material into the first mold, curing the first curable material, and removing the first curable material from the first mold. Then the patterned roller having the negative pattern is formed by coating a roller with a layer of a second curable material, pre-curing the second curable material to provide a viscous but not hardened surface, and rolling the roller over the second mold to create the negative pattern in the second curable material. The second curable material is then cured. Any of the curable materials may be coated after curing, preferably with metal, to reduce sticking in subsequent steps. The patterned roller may be used to create a pattern of microlenses in a third curable material. A substrate is coated with the third curable material. The patterned roller is rolled over the third curable material to transfer the pattern to the third curable material. The third curable material may then be cured.

    摘要翻译： 提供了图案化辊，以及制造图案辊的方法。 可以通过用蚀刻工艺在平坦模具表面中蚀刻凹坑来首先形成具有负图案的第一模具来制造图案化辊。 然后，通过将第一可固化材料倒入第一模具中，固化第一可固化材料，并从第一模具中除去第一可固化材料，形成具有正图案的第二模具。 然后，具有负图案的图案辊通过用一层第二可固化材料涂覆辊来形成，预先固化第二可固化材料以提供粘性但不硬化的表面，以及将辊滚动到第二模上以产生 第二可固化材料中的负图案。 然后固化第二可固化材料。 任何可固化材料可以在固化之后，优选用金属涂覆，以减少后续步骤中的粘附。 图案化辊可用于在第三可固化材料中产生微透镜图案。 用第三可固化材料涂覆基材。 图案化辊在第三可固化材料上滚动以将图案转移到第三可固化材料。 然后可以固化第三可固化材料。
