Graphene　(GP)　field　emitters　fabricated　by　the　electrophoretic　deposition　(EPD)　and　their　field　emission　performance　can　be　enhanced　and　tailed　simultaneously　by　chemical　doping　Au　nanoparticles　(NPs).　It　was　found　that　doped　Au　NPs　could　both　decrease　the　resistance　of　GP　emitters　and　increase　the　density　of　field　emission　sites.　The　Au-doped　GP　emitters　showed　lower　turn-on　voltage,　lower　threshold　field,　higher　field　enhancement　factor,　higher　luminance　intensity,　and　emitting　uniformity,　compared　with　that　of　pristine　GP.　This　study　will　provide　us　to　further　understand　the　role　of　doping　effect　on　the　GP　emitters　used　for　the　future　display.　(C)　2013　AIP　Publishing　LLC.
