Abstract：

The　exploration　of　suitable　phosphors　with　high　efficiency,　low　saturation,　and　good　stability　has　always　been　a　key　issue　for　field-emission　displays　(FEDs)　development.　In　this　work,　a　novel　Li2CaSi2N4:Eu2+　orange-red　phosphors　were　prepared　by　solid　reaction　process　and　the　cathodoluminescence　(CL)　properties　were　investigated　in　detail　to　explore　the　potential　application　for　FEDs.　Under　a　low　voltage　electron-beam　excitation,　the　phosphors　show　an　intense　orange-yellow　emission　in　the　range　of　500-700　nm,　which　belongs　to　the　4f65d→4f7　electron　transition　of　Eu2+　ion.　The　influences　of　the　Eu2+　doping　concentration,　filament　current,　accelerating　voltage,　and　bombardment　time　on　the　CL　emission　of　Li2CaSi2N4:Eu2+　were　investigated　in　detail.　The　results　indicate　that　Li2CaSi2N4:Eu2+　phosphors　exhibit　an　intense　orange-red　emission,　no　saturation　effect,　and　excellent　degradation　property,　which　give　the　Li2CaSi2N4:Eu2+　phosphors　potential　application　in　full　color　FEDs.　©　2018　The　American　Ceramic　Society
