    摘要： The invention relates to an electroluminescent device with a transparent cathode. Said electroluminescent device comprises a substrate (1) and, adjacent to said substrate (1), a laminated body composed of a first electrode (2), an electroluminescent layer (3) and a second metallic electrode (4). Said second electrode (4) is covered with transparent dielectric layers (5), which increase the transmission of light through the second metallic electrode (4) and serve as filters.

    摘要： An LED includes a substrate layer with a first surface and a second surface opposing the first surface and having a refractive index of n1. A light emitter is provided on the first surface and an array of particles is arranged on the second surface. The index matching layer between the particles on the second surface has a refractive index of n2being n2≧n1−0.5 and n2≦n1+3. Further, the filling height of the index matching layer is lower than the maximum height of the array of particles.

    摘要： The invention describes a light-emitting device which comprises at least a substrate (1), an anode (2), a first hole transport layer (3), a light-emitting layer (5) and a cathode (6), and in which a first hole blocking layer (4) is arranged between the first hole transport layer (3) and the light-emitting layer (5). The hole blocking layer (4) reduces the concentration of holes which reach the light-emitting layer (5) and thus the concentration of holes, which are usually the majority charge carriers, can be adapted to the electron current.

    摘要： The invention relates to an electroluminescent device, which comprises a first set of bands and a second set of bands, which are arranged in such a way, that they form a two-dimensional mesh with points of intersection between the bands of the first set and the bands of the second set. The bands in each case consist of a sequence of layers and at least one set of bands contains a light-emitting substance, which emits light when a voltage is applied. The band structure increases the contact areas between the individual bands and the light is generated more efficiently.
