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.

本研究工作的主要结果如下:9.1改善排放特性的有机EL器件的插入Aluminume氧化物薄FilmImprovement电极/有机界面一直在研究有机8 -羟基喹啉铝电致发光二极管由(Alqィイc15ィエD2)和二胺衍生物(兼总经理)。在有机层与电极（阳极或阴极）之间插入单层尺寸的氧化铝（Al′′φ D22′′φ D2O′′φ D23′′φ D2）层。提高发射效率一直在观察二极管与单层大小AlィイD22摊位ィエD2Oィイc15ィエD2层之间插入电极和有机层。9.2具有量子约束结构的有机电致发光器件利用染料分子的量子约束超晶格结构，有机电致发光二极管因其高强度、高效率而得到了广泛的研究，并表现出新的器件特性。在本研究中，利用8-羟基喹啉铝（Alq γ γ γ）和2-（4-联苯基）-5-（4-叔丁基苯基）1,3,4-恶二唑（PBD），实现了量子受限超晶格结构有机发光二极管的增强发射。9.3铕和氮杂合物的超结构强锐红发射铕配合物是有机发光二极管中有前途的锐红发射源之一。强锐发射可以应用于显示设备或光通信系统。由于铕配合物缺乏载流子输运能力，因此在发射层中采用超晶格结构非常重要。利用铕配合物/偶氮甲基配合物的超晶格结构，在614nm处获得了锐利的红色发射。
