Abstract: There is disclosed an organic light-emitting device having at least one layer of light-emissive organic material arranged between first and second electrodes, one of the first and second electrodes being a multilayer structure, each layer of the multilayer structure being a DC magnetron sputtered layer. There is also disclosed an organic light-emitting device having two or more layers of light-emissive organic material arranged between first and second electrodes, an uppermost layer of the organic material being more resistant to sputter deposition than an underlying layer of the organic material, and the electrode formed over the uppermost layer of organic material being a sputtered layer. There are also disclosed methods for making such structures.
Abstract translation: 公开了一种有机发光装置，其具有布置在第一电极和第二电极之间的至少一层发光有机材料，第一电极和第二电极中的一个为多层结构，多层结构的每一层为DC磁控溅射 层。 还公开了一种有机发光装置，其具有布置在第一和第二电极之间的两层或更多层发光有机材料，有机材料的最上层比有机材料的下层更耐溅射沉积， 并且形成在最上层的有机材料上的电极是溅射层。 还公开了制造这种结构的方法。

Abstract: An electroluminescent device comprising: a first charge carrier injecting layer for injecting positive charge carriers; a second charge carrier injecting layer for injecting negative charge carriers; and a light-emissive layer located between the charge carrier injecting layers and comprising a mixture of: a first component for accepting positive charge carriers from the first charge carrier injecting layer; a second component for accepting negative charge carriers from the second charge carrier injecting layer; and a third, organic light-emissive component for generating light as a result of combination of charge carriers from the first and second components; at least one of the first, second and third components forming a type II semiconductor interface with another of the first, second and third components.
