| 제목 | Fabrication of High Relative Quantum Efficiency Electroluminescence Devices Prepared by Spin Self-assembly Method |
| 초록 | In this study, we prepared three kinds of PPV (poly(p-phenylene vinylene)) based EL devices via three different methods and evaluated the film properties as well as device performance (i.e., in terms of relative quantum efficiency). Samples were fabricated by following methods: PPV single thick layer by spin casting, PPV/PMA (poly(methacrylic acid)) multilayer using a dip SA method, and PPV/PMA multilayer using a spin SA method. The film thickness were characterized by ellipsometry and their electrical and luminescent properties were measured by current-voltage source measurement unit and photoluminescence spectroscopy. We have demonstrated that the well-ordered multilayer thin films could be produced in a very short time using a spin self-assembly (SA) method. And also using this method, we can exactly control the layer thickness and make multilayer thin film with a low degree of interpenetration. So, we can make the 'Organic Multiple Quantum Well (OMQW)' like structure using a spin SA method. In this structure, electron & hole recombination probability increases, so relative quantum efficiency increases. Since EL devices fabricated by spin SA method have higher relative quantum efficiency than other methods. |
