Improvement of electrode/organic interface has been studied in organic electroluminescent diodes which consist of 8-hydroxyquinoline aluminum (Alq3) and diamine derivative (TPD). Mono-layer size aluminum oxide (Al2O3) layer was inserted between TPD and indium tin oxide (ITO) anode. The improvement of emission has been observed in the diode with Al2O3 layer of 0.5-1nm in thickness inserted in the interface of anode metal and organic molecule. The mechanism of increase in emission efficiency has been discussed.
