Abstract：

In　this　work,　Pr3+　and　Tb3+　coactivated　Na5Gd(WO4)4　(NGW)　phosphors　have　been　synthesized　by　high-temperature　solid-state　reactions　and　the　scheelite　crystal　structure　was　determined　for　the　first　time.　A　color-tunable　emission　in　NGW:　Pr3+,　Tb3+　phosphors　can　be　realized　by　the　modulation　of　excitation　wavelengths,　namely,　the　fluorescence　intensity　ratio　of　Pr3+　to　Tb3+　in　this　material　could　be　changed　by　different　excitation.　With　increasing　temperature,　the　luminescence　of　NGW:　Pr3+,　Tb3+　phosphor　decreases　almost　linearly　with　the　CIE　coordinate　variation　from　(0.306,　0.392)　to　((0.375,　0.465)　and　result　in　the　color　of　the　photoluminescence　variation　from　the　blue-green　to　yellow.　These　results　demonstrated　that　the　investigated　phosphors　are　attractive　for　application　in　display　lighting　and　optical　temperature　sensing.　©　2018
