英文摘要The effects of Co ions substitution on the structural, multiferroic, dielectric, and optical properties of Aurivillius Bi5FeTi3O15 are investigated. High resolution transmission electron microscope measurements imply that Bi5FeTi2Nb0.5CO0.5O15 (BFTNCO) exhibits a typical four-layered Aurivillius structure. The co-doping of Nb/Co ions at Ti sites is found to induce the lattice distortion. In comparison with Bi5FeTi3O15 and Bi5Fe0.5CO0.5Ti3O15, the sample BFTNCO shows a more superior multiferroicity with the remanent magnetization M-r and polarization P-r of 76.4 memu/g and 10.2 mu C/cm(2), respectively. The improved multiferroicity can be ascribed to reduced oxygen vacancy, large lattice distortion and large grain size. In addition, a relatively narrow optical band gap E-g can be obtained as 2.30 eV for BFTNCO. The decreased E-g in BFTNCO can be attributed to large lattice distortion and the overlap of Co 3d state with Ti t(2g) state. These results reveal that Ti-site doped Aurivillius phase may be the potential candidates for exploring excellent room-temperature multiferroics with narrow band gap.
