Abstract
Wire-coated graphite electron emitters are disclosed. These field emitters find particular usefulness in field emitter cathodes, display panels and lighting devices. These graphite field emitters can be formed by coating a paste comprised of graphite and glass frit onto the wire, firing the paste and bombarding the fired product with an ion beam.
