The　fabrication　and　luminescent　properties　of　novel　Na2YMg2V3O12:Eu3+　phosphors,　obtained　by　a　conventional　solid-state　reaction,　were　investigated.　The　self-activated　emission　of　the　Na2YMg2V3O12　host　exhibits　a　broad　emission　band　ranging　from　400　to　700　nm　with　a　maximum　peak　at　530　nm,　ascribed　to　the　d-d　transition　(T-3(2),　T-3(1)　-＞(　1)A(1))　of　V5+　ions　in　the　(VO4)(3-)　groups.　On　excitation　with　near-UV　(365　nm)　light,　the　Na2YMg2V3O12:　Eu3+　phosphors　emit　bright　red　light,　including　both　the　broad　emission　band　of　the　(VO4)(3-　)groups　and　the　sharp　emission　peaks　of　Eu3+　ions.　At　a　quenching　concentration　of　0.20　mol,　the　Eu3+　ion　emission　peaks　were　located　at　597,　613,　654　and　710　nm.　The　thermal　stability　of　the　as-prepared　Na2YMg2V3O12:Eu3+　phosphor　was　studied　and　the　thermal　quenching　activation　energy　(?E)　was　calculated　to　be　0.33　eV.　Furthermore,　a　designed　and　packaged　white-light-emitting　diode　(WLED)　lamp,　fabricated　with　the　obtained　phosphors,　commercial　(Ba,　Sr)(2)SiO4:Eu2+　green　phosphors,　BaMgAl10O17:Eu2+　blue　phosphors　and　a　near-ultraviolet　(n　-UV)　chip,　emitted　bright　white　light　with　a　CIE　coordinate　of　(0.3068,　0.3491),　CRI　of　88.20　and　CCT　of　4460　K.　These　results　indicate　the　potential　of　the　as-prepared　Na2YMg2V3O12:Eu3+　phosphor　as　a　red-emitting　phosphor　for　solid-state　illumination.
