  • Publication number: 20090309481
    Abstract: The present invention relates to methods for fabricating a cathode emitter and a zinc oxide anode for a field emission device to improve the adhesion between emitters and a substrate and enhance the luminous efficiency of a zinc oxide thin film so that the disclosed methods can be applied in displays and lamps. In comparison to a conventional method for fabricating a field emission device, the method according to the present invention can reduce the cost and time for manufacture and is suitable for fabricating big-sized products. In addition, the present invention further discloses a field emission device comprising a zinc oxide/nano carbon material cathode, a zinc oxide anode and a spacer.

  • Publication number: 20080248430
    Abstract: A nano-carbon material field emission cathode plate is prepared by an oxidation-reduction reaction, which includes immersing a substrate having a first metal layer thereon in a solution of a second metal salt with a nano-carbon material dispersed therein. A difference between the two standard redox potentials of the first metal and the second metal is so great that ions of the second metal in the solution are reduced to elemental metal while the first metal is oxidized, and thus a layer of the second metal is formed on the first metal layer with the nano-carbon material partially embedded in the second metal layer.
