Abstract
A method is provided for producing organic electrical layers having organic emitters that are phosphorescent at room temperature. Organic fluorescent emitters, together with organic complex ligands containing metal complexes, and at least one heavy main group metal, selected from the group comprising In, Tl, Sn, Pb, Sb and Bi, are deposited jointly inside a layer, and the heavy main group metal changes its coordination sphere by receiving the organic fluorescent emitter.
