A　new　rare-earth　oxyborate　Ba3BiPbEuO(BO3)(4)　was　prepared,　and　its　crystal　structure　was　established　by　the　single-crystal　X-ray　diffraction　method　with　the　following　structural　data:　P6(3)/mmc,　a　=　5.4305(1)　angstrom,　c　=　26.3501(3)　angstrom,　V　=　672.96(3)　angstrom(3)　and　Z　=　2.　This　is　a　layered　material　containing　two　types　of　layers:　one　is　formed　by　corner-sharing　EuO6　octahedra　and　BO3　triangles　and　the　other　is　composed　of　corner-　or　edge-sharing　(Bi/Pb)O-7　hexagonal　pyramids　and　BO3　triangles.　These　layers　and　their　equivalent　partners　are　alternately　stacked　along　the　c-axis,　with　Ba2+　cations　situated　in　between　and　within　the　layers.　Furthermore,　the　phase　composition,　morphology,　and　IR,　Raman,　XPS,　and　UV-vis　absorption　spectra　of　this　compound　were　studied.　In　addition,　solid　solutions　of　Ba3BiPbY1-xEuxO(BO3)(4)　(0　＜=　x　＜=　1)　were　prepared　via　the　solid-state　reaction　method　and　their　photoluminescence　properties　were　investigated.　Ba3BiPbYO(BO3)(4)　and　Ba3BiPbEuO(BO3)(4)　showed　blue　and　reddish-orange　luminescence　when　excited　at　242　and　394　nm,　respectively.　By　doping　Eu3+　into　the　Ba3BiPbYO(BO3)(4)　matrix　and　changing　the　Eu3+　doping　concentration,　luminescence　color　tunability　from　blue　to　orange-red　was　realized　in　Ba3BiPbY1-xEuxO(BO3)(4)　phosphors　under　excitation　at　331　nm.　This　kind　of　material　with　color　variability　may　have　potential　application　in　field-emission　displays.
