Vertically aligned carbon nanotubes (CNTs) have been synthesized by chemical vapor deposition at low temperatures between 450°C to 550°C for use as display emitters. It has been found that preheating the reaction gas C2H2 at 700°C enhances its reactivity and contributes to the effective decomposition of the gas on the surfaces of catalyst particles heated even at 450°C. We have also found that the catalyst activity is strongly affected by the film thickness and the thickness ratio of layered catalysts, which are Co and Ti in this study. Long CNTs have been obtained when the thicknesses of Co and Ti are reduced. It has been observed that the turn-on voltage of the field emission from the CNTs prepared at low temperatures is similar to that from the CNTs prepared at high temperatures.
