In　this　study,　novel　Eu3+-,　Dy3+-,　and　Sm3+　-activated　Na3La(VO4)(2)　phosphors　were　synthesized　using　a　solid　state　reaction　method.　X-ray　diffraction　analysis　results　indicated　that　the　Na3La(VO4)(2)　phosphors　had　an　orthorhombic　crystal　structure　with　the　Pbc21　space　group.　There　were　two　different　La(1)O-8　and　La(2)O-8　polyhedra　with　high　asymmetry　in　the　crystal　structure.　Scanning　electron　microscopy　revealed　that　the　product　had　a　sheet　morphology　with　an　irregular　particle　size.　Further,　the　luminescence　properties,　including　the　excitation　and　emission　spectra,　and　luminescence　decay　curve,　were　investigated　using　a　fluorescence　spectrometer.　The　results　showed　that　the　Na3La(VO4)(2)　compound　was　an　excellent　host　for　activating　the　luminescence　of　Eu3+　(614　nm),　Dy3+　(575　nm),　and　Sm3+　(647　nm)　ions.　Further,　Dy3+/Eu3+　co-doped　Na3La(VO4)(2)　phosphors　were　exploited,　and　the　energy　transfer　from　Dy3+　to　Eu3+　was　demonstrated　in　detail　by　the　photoluminescence　excitation,　photoluminescence　spectra,　and　luminescent　decay　curves.　The　results　showed　that　the　energy　transfer　efficiency　from　Dy3+　to　Eu3+　was　highly　efficient,　and　the　energy　transfer　mechanism　was　dipole-dipole　interactions.　Finally,　tunable　emissions　from　the　yellow　region　of　CIE　(0.3925,　0.4243)　to　the　red　region　of　CIE　(0.6345,　0.3354)　could　be　realized　by　rationally　controlling　the　Dy3+/Eu(3+)concentration　ratio.　These　phosphors　may　be　promising　materials　for　the　development　of　solid-state　lighting　and　display　systems.
