Abstract: An electroluminescent layer arrangement having a light-emitting organic material arranged between two electrodes which can be connected to a DC voltage source, a first electrode being a hole-injecting electrode (anode) and a second electrode being an electron-injecting electrode (cathode). The hole-injecting electrode and/or the electron-injecting electrode consist, at least locally, of a nanomaterial.

Abstract: An electroluminescent system, includes a light emitting substance which emits light when an electric voltage is applied thereto and which contains (a) inorganic particles which are clustered to provide inorganic clusters; and (b) organic ligand envelopes which are composed of an organic ligand material and which each envelope an inorganic cluster whereby the inorganic clusters are stabilized. The light emitting substance may additionally contain organic molecule chains which connect organic ligand envelopes to one another. Thus, the inorganic clusters are spaced apart by a spacing which may be preselected by providing organic molecule chains having a preselected number of atoms in the organic molecule chains.
