Conductive　films　are　an　essential　component　in　surface-conduction　electron　emitters　(SCEs),　and　they　have　a　major　influence　on　the　electron　emission　properties　of　SCEs.　In　this　work,　a　novel　PdO-C-PdO　multilayer　film　deposited　by　magnetron　sputtering　is　proposed　as　the　conductive　film　in　SCEs.　Three　SCE　cathodes　with　this　type　of　multilayer　film　were　fabricated,　together　with　three　other　SCE　cathodes　with　a　PdO　single-layer　film　used　as　a　reference.　For　these　cathodes,　the　dependences　of　the　conduction　current　and　the　emission　current　on　the　device　voltage　and　the　anode　voltage　were　measured,　and　the　luminescence　patterns　were　observed　after　the　electroforming　and　activation　processes　of　the　conductive　films　had　occurred.　The　surface　morphologies　of　the　conductive　films　were　analyzed　by　scanning　electron　microscopy.　The　results　indicate　that　the　SCEs　with　the　PdO-C-PdO　multilayer　conductive　film　have　better　electron　emission　properties　compared　with　the　SCEs　with　the　PdO　single-layer　conductive　film.　For　an　anode　voltage　of　2　kV　and　a　device　voltage　of　14　V,　the　emission　current　and　the　electron　emission　ratio　of　the　SCEs　with　the　PdO-C-PdO　multilayer　film　can　reach　179.5　mu　A　and　2.2　parts　per　thousand,　respectively.
