摘要：

A　new　rare-earth　borate　Na3-3δEu2+δ(BO3)3　(δ　=　0.16)　has　been　prepared　using　a　high　temperature　flux　method　and　structurally　characterized　by　single-crystal　X-ray　diffraction　analyses.　The　compound　crystallizes　in　the　orthorhombic　space　group　Amm2　with　a　=　5.08902　(11)　Å,　b　=　10.9754　(2)　Å,　c　=　7.01996　(14)　Å,　V　=　392.094　(14)　Å3,　and　Z　=　2.　It　features　a　three-dimensional　framework　constructed　by　interconnecting　NaO6,　EuO9,　(Na/Eu)O8　distorted　polyhedra,　and　BO3　planar　triangles.　Furthermore,　IR,　Raman,　XPS,　and　UV–vis　absorption　spectra　as　well　as　photoluminescence　properties　of　this　compound　were　studied.　Under　near-UV　excitation　(396　nm),　Na3-3δEu2+δ(BO3)3　(δ　=　0.16)　exhibits　an　intense　reddish-orange　emission　centered　at　around　614　nm　with　the　CIE　coordinates　of　(0.637,　0.363),　which　can　be　assigned　to　the　electric　dipole　5D0→7F2　transition　of　Eu3+　ions.　The　phosphor　shows　the　stable　luminescence　and　color　purity　at　elevated　temperature.　We　may　expect　it　to　be　a　potential　reddish-orange　phosphor　pumped　by　near-UV　LED　chips.　©　2021　Elsevier　Masson　SAS
