Abstract
An organic electroluminescent component having a layer composite, which comprrises a) a substrate layer b) a first transparent electrode layer, c) a mixing layer having c.1) a matrix of a conductive organic material with one or more singlet states and one or more triplet states, selected from the group: p-conductive and n-conductive materials, c.2) in this matrix, a light-emitting material which contains a metallo-organic complex compound with an emissive triplet state, and d) a second electrode, the lowest-energy triplet state of the conductive organic material being higher than the emissive triplet state of the metallo-organic complex compound by an energy difference Et.
