ABSTRACT:
A field emission double-plane light source includes a first anode, a second anode, and a cathode separately arranged between the first and second anodes. Each of the first and second anodes includes an anode substrate, an anode conductive layer formed on a surface of the anode substrate, and a fluorescent layer formed on the anode conductive layer. The cathode has a metallic based network with two opposite surfaces, each facing a respective one of the first and second anodes. Each of the surfaces of the network has a respective electron emission layer thereon facing a corresponding fluorescent layer of one of the first and second anodes. Each of the electron emission layers includes a glass matrix, and a plurality of carbon nanotubes, metallic conductive particles, and getter powders dispersed in the glass matrix. A method for making such field emission double-plane light source is also provided.
