ORGANIC LIGHT-EMITTING DEVICE AND METHOD FOR PRODUCING AN ORGANIC LIGHT-EMITTING DEVICE

摘要

The invention relates to an organic light-emitting part having a functional layer stack (10), which functional layer stack has a substrate (1), a first electrode (2) above the substrate, an organic functional layer stack (4) above the first electrode, having an organic light-emitting layer (5), and a second electrode (3) above the organic functional layer stack, wherein a layer (1, 2, 3) of the functional layer stack (10) forms a carrier layer (6) for a diffusion layer (7), wherein the diffusion layer (7) has at least one first and one second organic component (71, 72) having indices of refraction that differ from each other, wherein the first organic component (71) is hydrophobic and the second organic component (72) is hydrophilic, wherein the glass transition temperature of a mixture of the first organic component (71) and the second organic component (72); lies above the room temperature and wherein the first organic component (71) and the second organic component (72) are partially segregated in the diffusion layer (7) and the diffusion layer (7) has a mesoscopic boundary layer (75) between the first and second organic components (71, 72) or the diffusion layer (7) is present as a mesophase (78) having the first and second organic component (71, 72). The invention further relates to a method for producing an organic light-emitting part.
