Abstract
A process for making a field emitter cathode is disclosed, which comprises the steps of depositing a solution of a metal compound in a solvent and an electron emitting powder onto the surface of a substrate and heating the substrate containing the solution and the electron emitting powder deposited thereon for a time and temperature sufficient for the metal compound to be completely reduced to a metal.
