简介 The electroluminescent assembly comprises a first electrode film, together with an inorganic, electron conducting layer. There are one or more opto-electronically effective films, which have at least one light emitting film, with an organic emitter, and a second electrode film. The inorganic film contains an N-conductive oxide of a junction metal of the group of Ti, Zr, Hf, V, Nb, and Ta, preferably TiO2 or Nb doped SaTiO3. Typically the organic emitter is a rare earth metal complex with a carboxylate or phosphonate group.
