Abstract：

Dy3+　and　Tm3+/Dy3+:　NaY　(WO4)2　phosphors　have　been　synthesized　by　high-temperature　solid-phase　sintering　method.　X-ray　diffraction　(XRD)　andiphotoluminescenceti(PL)uproperties　of　the　phosphors　were　used　to　characterize　the　samples.　Under　UV　radiation　(352　nm)　excitation,　the　sample　Dy3+:　NaY　(WO4)2　phosphors　perform　a　blue　emission　at　474　nm　and　yellow　emission　at　574　nm,　and　the　intensity　of　blue　emission　is　significantly　weaker　than　that　of　yellow　emission.　The　sample　as　a　whole　shows　yellow　emission.　Tm3+　and　Dy3+　ions　co-doped　NaY　(WO4)2　sample　is　expected　to　obtain　the　better　color　purity　of　white　emission　because　the　emission　at　450　nm　corresponding　to　the　transition　1D2　·3F4　of　Tm3+　ions　can　effectively　improve　blue　emission　portion.　By　adjusting　the　doping　concentration　of　Tm3+　and　Dy3+ions,　the　better　color　purity　of　white　emission　is　obtained　from　Tm3+/Dy3+:　NaY　(WO4)2　phosphors.　The　study　on　the　luminescence　mechanism　showed　that　there　is　the　energy　transfer　between　Tm3+　and　Dy3+　in　Tm3+/Dy3+:　NaY　(WO4)2　phosphors.　©　2013　by　American　Scientific　Publishers　All　rights　reserved.
