A field electron emission material is created by applying a silica precursor to graphite particles (11); processing the silica precursor to produce amorphous silica (12) which is doped and/or is heavily defective, and disposing the graphite particles (11) upon an electrically conductive surface (14) of a substrate (13) such that they are at least partially coated with the amorphous silica (12).
L'invention concerne la production d'un matériau à émission d'électrons par effet de champ au moyen des étapes suivantes : on applique un précurseur de silice sur des particules (11) de graphite, on traite ce précurseur de silice afin de produire du silice (12) amorphe, ce dernier étant dopé et/ou présentant un grand nombre de défauts, puis on dispose les particules (11) de graphite sur la surface (14) électriquement conductrice d'un substrat (13), de manière à les enrober au moins partiellement avec ce silice (12) amorphe.
