Abstract：

Abstract:　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.　©　2022,　Pleiades　Publishing,　Ltd.
