Ail anodic aluminum oxide (AAO) template was formed by a two-step anodization process. Carbon nanotubes (CNTs) were Successfully synthesized along with AAO pares and the diameters of CNTs equaled those of AAO pores. The lengths of CNT's during a chemical vapor deposition synthesized process on the AAO template were effectively controlled. These AAO CNTs exhibit excellent Held emission with a low turn-on field (0.7V/mu m) and a low threshold field (1.4V/mu m). The Held enhancement factor, Calculated from the non-saturated region of the Fowler-Nordheim (F-N) plot, is about 8237. A novel field-emission organic light-emitting diode (FEOLED) combining AAO-CNTs cathodes as electron source with organic electroluminescent (EL) light-emitting layers coated oil indium-tin-oxide (ITO) is produced. The uniform and dense luminescence image is obtained in the FEOLEDs. Organic EL light-emitting materials have lower working voltage than inorganic phosphor-coated fluorescent screens.
