英文摘要 | Two isostructural compounds, Ba2SbO2SX (X=Br, I), have been successfully synthesized via solid state reaction. Their structures belong to the space group C-2h(2) - P21/m (No. 11) of the monoclinic system. They feature a quasi two- dimensional (2D) network of distorted capped trigonal prisms [XBa7](13+) along the a-b plane intercalated by (SbSO2)(3-) triangular pyramid. The optical band gaps of Ba2SbO2SBr and Ba2SbO2SI are 1.93 eV ad 2.03 eV, respectively. Ba2SbO2SI also exhibits an emission peak at 579 nm under 375 nm radiation. First-principles calculation reveals that the optical absorptions of Ba2SbO2SX are mainly attributed to the S-3p -> Sb-5p transitions. The photoluminescence emission of Ba2SbO2SI is mainly contributed by the excitation of the states of the Sb-S bonds. |
