Title: Crystal structure and Eu{sup 3+}/Tb{sup 3+} doped luminescent properties of a new borate Ba{sub 3}BiB{sub 9}O{sub 18}

Abstract

Undoped and doped either by Eu{sup 3+} or Tb{sup 3+} bismuth borate Ba{sub 3}BiB{sub 9}O{sub 18} was structurally characterized and analyzed by fluorescence spectroscopy. Belonging to synthetic borate member of the family Ba{sub 3}XB{sub 9}O{sub 18}, layers of planar triangular B{sub 3}O{sub 6} groups connecting with deformed BaO{sub 6} hexagons are interleaved by 9-coordinate Ba atoms, and 6-coordinate Bi atoms. Its crystal structure was determined and refined from powder X-ray diffraction data by the Rietveld method and the results showed that Ba{sub 3}BiB{sub 9}O{sub 18} belongs to space group P6{sub 3}/m with unit cell dimensions of a = 7.1999(2) A, c = 17.3567(6) A, and z = 2. Curves of differential thermal analysis and thermogravimetric analysis showed that Ba{sub 3}BiB{sub 9}O{sub 18} is a congruent melting compound and chemically stable above 728 {sup o}C. Ba{sub 3}Bi{sub 1-x}Eu{sub x}B{sub 9}O{sub 18} and Ba{sub 3}Bi{sub 1-x}Tb{sub x}B{sub 9}O{sub 18} form a continuous solid solution from x = 0.01 to x = 0.9. The ultraviolet excited photoluminescence intensity increased with both Eu{sup 3+} and Tb{sup 3+} concentration in the matrix of Ba{sub 3}BiB{sub 9}O{sub 18}. There may be an interesting correlation between spectroscopic properties and lattice structural features of doped Ba{sub 3}BiB{sub 9}O{submore » 18}.« less
