Abstract:
1. A method for making a field emission double-plane light source comprising: (a) providing a plurality of carbon nanotubes, metallic conductive particles, glass particles and getter powders, a metallic based network, a pair of anodes, and a plurality of supporting members, each of the anodes comprising an anode conductive layer and a fluorescent layer formed on the anode conductive layer; (b) mixing the nanotubes, the metallic conductive particles, the glass particles, and the getter powders in an organic medium to form an admixture; (c) forming layers of the admixture on an upper surface and a bottom surface of the network; (d) drying and baking the admixture at a temperature of about 300° C. to about 600° C. to soft and melt the glass particles to result in glass matrixes on the upper surface and the bottom surface of the network, thereby yielding a cathode; and (e) thereafter, assembling and sealing the anodes, the cathode, and the supporting members together to obtain the field emission double-plane light source.
