ORGANIC ELECTROLUMINESCENT DEVICE AND A METHOD OF PRODUCING AN ORGANIC ELECTROLUMINESCENT DEVICE

摘要

An organic electroluminescent device comprises a substrate (1), a first electrode (2) arranged on the substrate (1), a functional organic layer (3) arranged on the first electrode (2), wherein the functional organic layer (3) is adapted to emit electromagnetic radiation, a second electrode (4) arranged on the functional organic layer (3), wherein the functional organic layer (3) comprises a matrix material and an emitter material, wherein the emitter material is neutral or ionically charged, wherein the emitter material is selected from the group of ionic transition metal complex, neutral transition metal complex, polymer emitter and combinations thereof, wherein the matrix material comprises at least one ionic charge carrier transporting material, wherein the ionic charge carrier transporting material is selected from the group of electron-transporting material, hole-transporting material, ambipolar-transporting material and combinations thereof, and wherein the at least one ionic charge carrier transporting material is ionically charged.
