摘要：

A new rare-earth oxyborate Ba3BiPbEuO(BO3)(4) was prepared, and its crystal structure was established by the single-crystal X-ray diffraction method with the following structural data: P6(3)/mmc, a = 5.4305(1) angstrom, c = 26.3501(3) angstrom, V = 672.96(3) angstrom(3) and Z = 2. This is a layered material containing two types of layers: one is formed by corner-sharing EuO6 octahedra and BO3 triangles and the other is composed of corner- or edge-sharing (Bi/Pb)O-7 hexagonal pyramids and BO3 triangles. These layers and their equivalent partners are alternately stacked along the c-axis, with Ba2+ cations situated in between and within the layers. Furthermore, the phase composition, morphology, and IR, Raman, XPS, and UV-vis absorption spectra of this compound were studied. In addition, solid solutions of Ba3BiPbY1-xEuxO(BO3)(4) (0 <= x <= 1) were prepared via the solid-state reaction method and their photoluminescence properties were investigated. Ba3BiPbYO(BO3)(4) and Ba3BiPbEuO(BO3)(4) showed blue and reddish-orange luminescence when excited at 242 and 394 nm, respectively. By doping Eu3+ into the Ba3BiPbYO(BO3)(4) matrix and changing the Eu3+ doping concentration, luminescence color tunability from blue to orange-red was realized in Ba3BiPbY1-xEuxO(BO3)(4) phosphors under excitation at 331 nm. This kind of material with color variability may have potential application in field-emission displays.
