A　set　of　colour　tuning　K2Ba(MoO4)(2):　Dy3+/Eu3+　(KBM:　Dy3+/Eu3+)　phosphors　were　fabricated　by　solid-state　method.　The　phase　purity　of　as-prepared　materials　was　validated　by　XRD　and　DRS　analyses.　The　KBM:　0.03Dy(3+)　sample　exhibits　two　major　luminescence　lines　at　481　and　572　nm　when　excited　by　351　nm　light,　corresponding　to　Dy3+　ions＇　typical　transitions　of　F-4(9/2)　-＞　H-6(J)　(J　=　15/2,　13/2).　By　introducing　Eu3+　ions　into　KBM:　0.03Dy(3+)　phosphor,　the　ET　from　Dy3+　to　Eu3+　ions　arises,　leading　to　colour　tuning　from　green　via　yellowish　green　to　pink　with　changing　Eu3+　ions＇　concentration,　along　with　the　lowest　CCT　of　KBM:　0.03Dy(3+)/0.03Eu(3+)　sample.　It　can　be　verified　by　PLE　and　PL　spectra　analysis　combined　with　the　decay　times　of　KBM:　0.03Dy(3+)/yEu(3+)　samples.　The　energy　transfer　mechanism　is　also　expounded.　Meanwhile,　the　emission　intensities　at　423　K　still　maintain　72.8%　for　Dy3+　ions　and　91.2%　for　Eu3+　ions　relative　to　303　K　of　the　KBM:　0.03Dy(3+)/0.03Eu(3+)　sample,　displaying　its　brilliant　thermal　stability.　All　these　results　connote　that　KBM:　Dy3+/Eu3+　phosphors　are　prospected　to　be　used　for　the　near-UV　excited　white　light-emitting　diodes.
