With　the　development　of　light-emitting　diodes　(LEDs)　display　and　lighting　industry,　new　requirements　have　been　put　forward　for　phosphors.　Traditional　syntheses　of　phosphors　face　the　problems　of　slow　temperature　increase,　long　holding　time　and　corresponding　larger　particle　size.　In　this　work,　a　co-precipitation　combined　with　induction　heating　method　was　developed　for　the　fast　and　efficient　synthesis　of　Lu2.97Al5O12:0.03Ce3+　(LuAG:0.03Ce)　phosphors.　The　effects　of　calcination　temperature　and　holding　time　on　the　morphology　and　luminescence　properties　were　investigated.　The　phosphor　synthesized　at　1600　°C　for　10　min　(10　min@1600　°C)　has　an　average　particle　size　of　500　nm,　and　exhibits　good　luminescence　properties　and　thermal　stability　(maintaining　92.04　%　of　room　temperature　light　intensity　at　200　°C).　The　luminescence　intensity　and　the　external　quantum　efficiency　(EQE)　of　the　phosphor　(60　min@1500　°C)　are　higher　than　those　of　a　commercial　phosphor.　The　light　source　fabricated　with　phosphor　ceramic　prepared　by　the　phosphor　(10　min@1500　°C)　shows　a　luminous　efficacy　(LE)　of　193　lm/W.　Therefore,　co-precipitation　combined　with　induction　heating　is　an　energy-saving　and　promising　method　for　the　synthesis　of　phosphor.　©　2024
