Abstract：

To　broaden　the　application　fields　of　phosphors,　multicolor　light-emitting　phosphors　are　considered　to　be　a　future　trend.　In　this　study,　multicolor　light　emission　was　successfully　achieved　in　Bi3+-activated　Lu3Sc2Ga3O12　(LSGO),　which　can　emit　a　narrow-band　blue　light　with　a　full　width　at　half　maximum　(FWHM)　of　42　nm　or　a　broad-band　cyan　light.　Significantly,　the　emitted　light　from　LSGO:　Bi3+　changed　from　cyan　to　blue　light　with　an　increase　in　the　excitation　wavelength.　Moreover,　differences　in　temperature-related　photoluminescence　properties　between　the　blue　and　cyan　light　were　detected,　indicating　the　potential　application　of　Bi3+-activated　LSGO　in　temperature　sensors.　The　origin　of　the　two　emission　bands　was　examined　in　detail　by　analyzing　the　crystal　and　electronic　structures　of　LSGO.　The　results　indicate　that　two　different　luminescent　centers　exist　in　LSGO:　Bi3+,　which　means　the　as-prepared　sample　could　have　broad　applications　in　many　fields.　©　2022　Elsevier　Ltd　and　Techna　Group　S.r.l.
