Light-emitting device with increased quantum efficiency |
| abstract |
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. |
