Abstract (en)
[origin: WO2015030627A1] A method for producing the emissive layer for an organic light emitting diode comprises dissolving a luminophore-containing compound and an organic conductive material in a common solvent, depositing a thin film of the resulting solution on a substrate and subsequently heat treating the deposited film at a temperature above 100C but below the emissive layer thermal decomposition temperature. The luminophore-containing compound may be a luminophore or a luminophore precursor that is transformable into a luminophore when heated. For example, the luminophore-containing compound may be a soluble ternary coordination compound containing a neutral ligand. The soluble ternary coordination compound is decomposed by heat treatment to form a luminophore; the neutral ligand is completely eliminated from the thin film by the heat treatment. The method allows emission layers to be obtained that contain an insoluble compound as the luminophore.
