| Research Abstract |
Conical nanoprotrusions whose sizes are smaller than the wavelength of visible light were fabricated on transparent plastic substrates by ion irradiation method at room temperature. This nanostructured substrate acted as a transparent and flexible electron emitter whose transmittance is higher than 90% at the visible light region. By combining this emitter with a zinc oxide based transparent phosphor film, a transparent field emission display was demonstrated. In addition, the graphitization process, such as carbon nanotube formation, by solid phase reaction during the field emission process for catalyst metal included carbon nanofibers was first observed by in situ transmission electron microscopy.
