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.
提供了一种生产有机电层的方法,该电层具有在室温下发出磷光的有机发光体。有机荧光发射体与含有金属络合物的有机络配体以及至少一种选自 In、Tl、Sn、Pb、Sb 和 Bi 组的主族重金属共同沉积在层内,主族重金属通过接收有机荧光发射体改变其配位层。
