Dy3+/Tb3+　co-doped　scheelite-type　Li2Y4(MoO4)(7)　(LYM)　based　phosphors,　which　exhibit　both　emissions　of　Dy3+　and　Tb3+　ions,　have　been　fabricated　via　the　solid　state　method.　The　phase　purity,　characteristics　of　luminescence,　UV-Vis　diffuse　reflectance　spectra,　energy　transfer　mechanism　as　well　as　decay　lifetimes　were　also　investigated.　The　resultant　samples　represent　color　tunable　emission　caused　by　the　energy　transfer　from　Dy3+　to　Tb3+　ions,　which　verified　that　the　LYM:Dy,Tb　phosphors　could　be　regarded　as　promising　materials　for　optical　display　system.
