The　Mg0.5-x-yTi2(PO4)(3):xTb(3+),　yEu(3+)　phosphors　were　synthesized　by　solid-state　reaction　method.　The　photoluminescence　excitation　spectra　and　the　luminescence　emission　spectra　of　Tb3+/Eu3+　single　doped　and　co-doped　Mg0.5Ti2(PO4)(3)　phosphors　have　been　measured.　The　energy　transfer　from　Tb3+　to　Eu3+　was　proved　by　emission　spectra,　excitation　spectra　and　decay　curves.　The　emission　colors　of　Mg0.5-x-yTi2(PO4)(3):xTb(3+),　yEu(3+)　phosphors　under　380　nm　excitation　are　located　at　purple　areas,　purplish　areas,　pink　areas　and　reddish　orange　areas.　The　results　of　color　coordinates　show　that　the　color-tunable　luminescence　can　be　realized　by　adjusting　the　concentrations　of　Tb3+　and　Eu3+　ions.　The　experiment　presents　that　single-component　Mg0.5-x-yTi2(PO4)(3):xTb(3+),　yEu(3+)　phosphors　are　promising　for　application　in　the　luminescence.　(C)　2017　Elsevier　GmbH.　All　rights　reserved.
