摘要：

Rare　earth　oxide　(REO)　doped　Molybdenum　metal　ceramic　emitters　were　successfully　prepared　by　the　air　Plasma　Spray　(APS)　method.　Microstructure　and　secondary　electron　emission　(SEE)　performance　were　investigated.　The　relative　uniform　mixing　of　rare　earth　oxide　and　molybdenum　have　been　observed.　The　maximum　secondary　electron　yield　is　3.3　after　activation　at　1100b(Mo　brightness　temperature)　in　vacuum.　©　2010　IEEE.
