Sol-Gel synthesis of SrBi₂Ta₂O₉ nanowires

We report the synthesis of perovskite ferroelectric nanowire strontium bismuth tantalate (SrBi₂Ta₂O₉, SBT). Sol-gel techniques have been used. The morphology and structures are analyzed via SEM, TEM and XRD. The XRD and TEM analysis show that the structure of SBT nanowires is single orthorhombic perovskite with A2₁am structure space group. The obtained SBT nanowires with an average length of 35 μm and a diameter of 200 nm are c-axis preferred orientation in the templates. The formation mechanism of SBT nanowires with complex crystal structure was discussed.
