Disclosed is an organic electroluminescent device, comprising: a) a substrate; b) a hole-injecting electrode (anode) coated over the substrate; c) a hole injection layer coated over the anode; e) a polymer based light emitting layer, coated over the hole transporting layer; f) a small molecule based light emitting layer, thermally evaporated over the polymer based light emitting layer; and g) an electron-injecting electrode (cathode) deposited over the electroluminescent polymer layer. |
