【Abstract】 Na0.5Bi0.5TiO3 nanowires with perovskite structure are synthesized by sol-gel-hydrothermal method,using sodium acetic,bismuth nitrate and titanium butoxide as the starting materials and NaOH as a mineralizer.The structure and components of Na0.5Bi0.5TiO3 nanowires were studied by means of X ray diffraction,transmission electron microscope,X ray photoelecron spectroscopy.Investigations show that the as-prepared samples are made up of large quantity nanowires with diameters of about 10~20 nm and lengths reaching up to 1 μm and singer crystalline in nature.The paper has also investigated the photoluminescence properties of Na0.5Bi0.5TiO3 nanowires.更多还原
