Patent ID: 8766238

Claim:
A light-emitting device comprising (i) an anode, (ii) a cathode and (iii) an emitter layer which is arranged between and in direct or indirect contact with the anode and the cathode and which comprises at least one charged emitter and an oppositely charged polymeric matrix, which interact with one another through electrostatic forces and wherein the emitter comprises a phosphorescent metal complex, clusters, metal-complex aggregates and/or fluorescent organic molecules wherein the emitter is selected from metal complexes of the formula formula (I) or (II) [(L CH ) x ML y ] n+ (I) [(L CH ) x ML y ] n− (II) in which: M is a metal ion selected from the group consisting of Mo, Ru, Rh, Pd, Ag, W, Re, Os, Ir, Pt, Cu, Au and lanthanoids; L CH is in each case independently a bidentate or polydentate chelate ligand; L is in each case independently a monodentate ligand; x is an integer from 1 to 3; y is an integer from 1 to 4; and n is an integer from 1 to 4 and is capable of having 3 to 15 volts applied to the device.
