A　series　of　Li2Eu4(MoO4)(7)　:　Bi3+　red　phosphors　were　prepared　by　a　sol-gel　method.　The　crystal　structures,　photoluminescence　properties,　energy　transfer,　decay　lifetimes　and　thermal　quenching　properties　were　also　explored.　Li2Eu4(MoO4)(7)　:　Bi3+　phosphors　could　be　excited　under　395　nm　near　UV　and　465　nm　blue　light　and　exhibit　bright　red　emission　located　at　615　nm.　The　luminescence　intensity　may　be　improved　because　of　energy　transfer　from　Bi3+　to　Eu3+　ions.　Li2Bi0.24Eu3.76(MoO4)(7)　phosphor　exhibits　good　thermal　stability,　short　lifetime　and　excellent　CIE　coordinates　which　could　be　a　promising　candidate　for　red　phosphors　for　WLEDs.
