A　series　of　novel　red　light-emitting　phosphors　Li2Y4-xEux　(MoO4)7　were　synthesized　by　a　solid-state　reaction.　The　optimal　synthesis　of　the　phosphors　via　sintering　occurred　at　850°C　for　4　h.　The　result　by　X-ray　diffraction　indicates　that　the　sample　is　a　pure　phase　of　Li2Y4(MoO4)7　crystal　structure　with　the　tetragonal　crystal　system.　The　photoluminescence　spectra　exhibit　that　the　sample　can　be　excited　effectively　by　a　near-ultraviolet　light　of　395　nm　and　a　visible　light　of　465　nm.　The　main　emission　peaks　located　at　615　nm,　corresponding　to　5D0→7F2　transition　of　Eu3+,　and　they　could　be　used　for　a　white　light　emitting　diode　(LED)　with　the　color　performance.　The　relative　intensity　of　the　sample　Li2Y1.2Eu2.8　(MoO4)7　reached　a　maximum　when　the　doped-Eu3+　quantity　x　was　2.8.
