| Abstract(in English) | New red or orange sulfide phosphors are studied. La2S3:Ce3+ and Y4(SiS4)3:Ce3+ were synthesized by solid-state reaction under vacuum or sulfur vapor atmosphere. Red or orange photoluminescence and cathodeluminescence were obtained from La2S3:Ce3+ or Y4(SiS4)3:Ce3+, respectively. Test devices of vacuum fluorescence display were prepared, and cathodeluminescence intensity was unfortunately as small as 10 cd m-2 at present. The atmosphere in the solid-state reaction of the phosphor synthesis changed the dependence of cathodeluminescence intensity on acceleration voltage. Ce3+ ions on the surface region in the phosphor powder are believed to be important for efficient cathodeluminescence. |
