Abstract: An organic light emitting functional device with organic electron injection layer to improve the injection of electrons from the cathode in an organic light emitting diode. In particular, the device relates to the use of electron transport layer 4,7-di phenyl-1,10 phenanthroline (herein after called as BPhen) and another organic semiconductor Tetracyano quino dimethane (herein after called as TCNQ) and optimizing the thickness and doping percentage of the composition in an organic light emitting device. The main use of the composed injection layer is to balance the injection of holes from the anode side and the injection of electrons from cathode side and thus increase the efficiency of Organic light emitting diodes.
