Abstract
The invention relates to an arrangement for an organic pin-type light-emitting diode with an electrode and a counter-electrode and a stack with organic layers between the electrode and the counter-electrode, where the stack with the organic layers comprises an emission layer comprising a k (k=1, 2, 3, . . . ) organic matrix materials, a doped charge carrier transport layer, which is arranged between the electrode and the emission layer, a further doped charge carrier transport layer, which is arranged between the counter-electrode and the emission layer, and one block layer, which is arranged between one of the doped charge carrier transport layers and the emission layer. The organic layers of the stack are formed by means of n (n≦k+2) organic matrix materials, where the n organic matrix materials comprise the k organic matrix materials of the emission layer. The stack with the organic layers can also be executed in a block-layer-free manner, where then the emission layer and the doped charge carrier transport layer are formed from an organic matrix material. Furthermore, a method for manufacturing such arrangements is stated.
