A field electron emission material is created by applying a silica precursor to graphite particles (); processing the silica precursor to produce amorphous silica () which is doped and/or is heavily defective, and disposing the graphite particles () upon an electrically conductive surface () of a substrate () such that they are at least partially coated with the amorphous silica ().

Method of creating a field electron emission material

A sealing glass paste which comprises at least one sealing glass frit powder and an aqueous binder which comprises an aqueous solution, dispersion or emulsion of a polymeric material and a water soluble oxidant which decomposes at a temperature of below 475&deg; C., the polymeric material burning out or decomposing at a temperature of below 475&deg; C., in the presence of the oxidant, to leave less than 2% of residues based on the total weight of the solids content of the binder. The sealing glass pastes may be used in the assembly of cathode ray tubes. The aqueous binder system which is used results in low carbonaceous residue levels after firing and does not contain volatile organic solvents. Furthermore, using this aqueous binder system sealing glass pastes can be prepared with sealing glasses which include PbO therein.
