A new sodium samarium borate with composition Na3Sm2(BO3)3 (NSBO) has been synthesized by high temperature solid state reaction. The yellowish transparent single crystals of Na3Sm2(BO3)3 have been grown from the Na2CO3-H3BO3 flux system using the top-seeded solution growth (TSSG) method. X-ray diffraction analysis demonstrated that the NSBO crystals belong to orthorhombic systems and lattice parameters are a=5.0585 Å, b=11.0421 Å, c=7.0316 Å. The measurement of the infrared spectrum indicated that the basic anionic groups are the BO3−3 groups. Furthermore, Na3Sm2(BO3)3 exhibits an optical second harmonic generation effect which is close to that of KDP (KH2PO4). 相似文献
