Claims18
A field emission device comprising an anode that comprises (a) a layer of phosphor material, and (b) disposed on the phosphor layer a layer prepared from one or more members of the group of protective materials consisting of amorphous carbon, graphite, diamond-like carbon, fullerenes, carbon nanotubes, a (co)polymer and an organic coating compound.
A field emission device comprising an anode that comprises layer that is prepared from a mixture of (a) phosphor materials, and (b) one or more members of the group of protective materials consisting of amorphous carbon, graphite, diamond-like carbon, fullerenes, carbon nanotubes, a (co)polymer and an organic coating compound.
A method of fabricating a field emission device comprising (a) providing as the anode therein a substrate, and (b) coating on the substrate a layer formed from a mixture of (i) phosphor material, and (ii) one or more members of the group of protective materials consisting of amorphous carbon, graphite, diamond-like carbon, fullerenes, carbon nanotubes, a (co)polymer and an organic coating compound.
A method of fabricating a field emission device comprising (a) providing as the anode therein a substrate, (b) coating on the substrate a layer formed from phosphor material, and (c) coating on the phosphor layer a layer formed from one or more members of the group of protective materials consisting of amorphous carbon, graphite, diamond-like carbon, fullerenes, carbon nanotubes, a (co)polymer and an organic coating compound.
