Abstract：

Ag-CNT　(carbon　nanotube)　composite　cathodes　are　prepared　on　elaborate　metal　electrodes　by　electrophoresis　and　screen　printing.　The　effects　and　conductive　mechanism　of　nano-Ag　on　field　emission　properties　of　CNT　cathodes　are　investigated.　The　morphologic　images　of　nano-Ag　film　and　Ag-CNT　composite　cathode　are　observed　by　scanning　electronic　microscopy　(SEM).　It　is　found　that　the　nano-Ag　particles　are　uniform　and　compact.　The　nano-Ag　particles　move　to　CNT　cathode　and　fill　up　the　contacting　vacancy　between　CNT　cathode　and　metal　electrodes　after　co-sintered.　So　electronic　transmission　and　heat　transfer　is　improved　between　CNT　cathode　and　metal　electrodes.　The　experimental　result　show　that　the　field　emission　properties,　luminance　and　stability　of　CNT　cathodes　could　be　improved　by　the　nano-Ag　conductive　film.
