Outline of Final Research Achievements

To develop optically-active organic light emitting diodes, we propose a usage of the chiral molecule-covered noble-metal nanoparticles. As a trial, we have investigated interactions between the metal surface and chiral molecules to elucidate their structure, optical property/dissymmetry at nanoscale. From the obtained results, we propose to introduce buffer layers between them to realize and keep the effective plasmon-resonance field. In addition, as a new transparent anode electrode, the reduced graphene 10 nm-sheet was proposed and its charge transport property was investigated, indicating that it was promising for the fabrications of future flexible and light-weight OLED.
