| abstract |
The invention relates to a method for producing phosphorescent emitter layers composed of at least one organic fluorescent emitter F and at least one metal complex K comprising organic complex ligands L and at least one heavy main group metal M selected from the group consisting of In, Tl, Sn, Pb, Sn and Bi, wherein the organic fluorescent emitter F and the metal complex K are each individually deposited as layers on a substrate and subsequently each caused to react together, wherein the coordination sphere of the heavy main group metal M is changed by receiving the organic fluorescent emitter F. |
