1. A field emission lamp comprising:

  • a transparent bulb having an open end;

    a lamp head disposed on the open end of the bulb;

    an anode comprising an anode conductive layer, a fluorescent layer, and an anode electrode, the anode conductive layer being formed on an inner surface of the bulb, the fluorescent layer being created on a portion of a surface of the anode conductive layer to result in an exposed portion of the anode conductive layer, the anode electrode being disposed on the open end of the bulb, the anode electrode electrically connecting the anode conductive layer with the lamp head; and

    a cathode comprising a cathode electrode and an electron emission element, an end of the cathode electrode being disposed in the open end of the bulb and insulated from the anode electrode, the cathode electrode being electrically connected with the lamp head, the electron emission element being disposed on an opposite end of the cathode electrode and electrically connected therewith, the electron emission element having an electron emission layer thereon, the electron emission layer being comprised of a glass matrix and a plurality of carbon nanotubes, getter powders, and metallic conductive particles dispersed therein.
