摘要：

A　new　kind　of　pressed　scandate　dispenser　cathode　was　fabricated　by　liquid-liquid　doping　using　a　Sol-Gel　technique.　The　cathode　exhibits　high　emission　property.　i.e.,　the　emission　current　density　reached　47A/cm2　at　850b　with　lower　Richardson　work　function　about　1.1-1.2eV　and　Ba:Sc:O　concentration　ratio　at　the　cathode　surface　was　1.6:1:2.0.　©　2008　IEEE.
