A　new　rare-earth　orthoborate　Ba2CdSm2(BO3)4　was　prepared　using　the　high　temperature　molten　salt　method　and　structurally　characterized　by　single-crystal　XRD　analysis　with　following　crystallographic　data:　Pna21,　a　=　7.6621(1)　angstrom,　b　=　26.2866(4)　angstrom,　c　=　16.4563(3)　angstrom,　V　=　3314.47(9)　angstrom　3,　and　Z　=　12.　It　exhibits　a　complicated　three-dimensional　framework　constructed　from　(Cd/Sm)On　(n　=　7,　8,　and　9)　distorted　polyhedra　and　BO3　planar　tri-angles,　with　the　open　channels　and　the　pockets　on　the　wall　of　the　channels　hosting　Ba2+　and　Ba2+/Sm3+　cations.　In　addition,　the　phase　purity,　morphology,　IR,　Raman,　XPS,　UV-vis　absorption　spectra　and　luminescent　properties　of　this　compound　were　studied.　Upon　excitation　at　401　nm,　Ba2CdSm2(BO3)4　displays　the　orange-red　emission　with　CIE　coordinates　of　(0.5869,　0.4122),　which　is　associated　with　the　characteristic　transitions　from　the　excited　state　4G5/2　to　the　ground　state　6HJ　(J　=　5/2,　7/2,　9/2,　11/2)　of　Sm3+　ion.　The　phosphor　shows　the　stable　luminescence　at　elevated　temperature,　and　its　room　temperature　fluorescent　decay　profile　exhibits　a　biexpo-nential　shape　with　the　average　lifetime　of　0.7297　ms.　As　it　is　expected,　Ba2CdSm2(BO3)4　may　be　a　potential　orange-red　phosphor　under　near-UV　light　excitation.
