Abstract :
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).
