Main results of this research work are as follows :9.1 Improvement of Emission Characteristic of Organic EL Device by Insertion of Aluminume Oxide Thin FilmImprovement of electrode/organic interface has been studied in organic electroluminescent diode which consists of 8-hydroxyquinoline aluminum (AlqィイD23ィエD2) and diamine derivative (TPD). Mono-layer size aluminum oxide (AlィイD22ィエD2OィイD23ィエD2) layer was inserted between organic layer and electrode (anode or cathode). Improvement of emission efficiency has been observed in the diode with mono-layer size AlィイD22ィエD2OィイD23ィエD2 layer inserted between electrode and organic layer. The mechanism of increase in emission efficiency has been discussed.9.2 Organic EL Device with Quantum-Confined StructureOrganic electroluminescent (EL) diodes have been extensively studied for high intensity, high efficiency and have been developed to exhibit novel device characteristics utilizing quantum confined superlattice structure of dye molecules. In this study, enhanced emission from organic EL diodes with quantum confined superlattice structure has been realized utilzing 8-hydroxyquinoline aluminum (AlqィイD23ィエD2) and 2-(4-biphenylyl)-5-(4-tert-butylphenyl)1,3,4-oxadiazole (PBD).9.3 Strong Sharp Red Emission from superstructure of Europium and Azmethin complexEuropium complex in one of the promising candidate for sharp red emission source in organic light emitting diodes. Strong sharp emission can be expected to apply to the display devices or optical communication systems. Since europium complex lacks carrier transport ability, it is important to employ a superlattice structure in the emissive layer. Sharp red emission at 614nm has been obtained from the EL device utilizing europium complex/azomethin complex superlattice structure.
