Sodium samarium borate Na3Sm(BO3)2, was prepared by a flux method and structurally characterized by single-crystal structure analysis for the first time. The results show that it crystallizes in the monoclinic system P21/n, with a = 6.5667(3) Å, b = 8.7675(4) Å, c = 10.1850(5), β = 90.86°, V = 586.32(5) Å3 and Z = 4. The structure contains NaO7, NaO6, NaO5, SmO8, and BO3 units, which are interconnected via corner- or edge-sharing O atoms into a three-dimensional structure. The excitation spectra, emission spectra, decay time, and Commission International de l’Éclairage (CIE) chromaticity index of Na3Sm(BO3)2 were studied. Under near light excitation (406 nm), the powdered Na3Sm(BO3)2 shows the orange-red emission, which originates from the 4G5/26H9/2 and 4G5/26H7/2 transformation of Sm3+ ion. View Full-Text
