Nd 做了 multiferroic BiFeO3 (Bi0.94Nd0.06FeO3 (BNF )) nanotubes 被一个大音阶的第五音胶化模板方法成功地综合。电子显微镜学调查展出了那这些 nanotubes 与大约 200 nm 的直径和大约 20 nm 的墙厚度有直、光滑的侧面。BNF 的 perovskite 类型结构被高分辨率的传播电子显微镜学在 nanotubes 证实并且选择了区域电子衍射分析。这些 nanotubes 有高抵抗力。nanotubes 的绝缘的经常、绝缘的损失分别地在 1 MHz 是 126 和 0.040。这些 BNF nanotubes 的铁电体性质与 48 C/cm2 的残余极化和 163 kV/cm 的一个强制电场被表明。
Nd doped multiferroic BiFeO3 (Bi0.94Nd0.06FeO3 (BNF)) nanotubes were successfully synthesized by a sol-gel template method. Electron microscopy investigations exhibited that these nanotubes had straight and smooth profile with diameters of about 200 nm and wall thickness of about 20 nm. A perovskite-type structure of BNF was confirmed in the nanotubes by high-resolution transmission electron microscopy and selected area electron diffraction analysis. These nanotubes had high resistivity. The dielectric constant and dielectric loss of the nanotubes were 126 and 0.040 at 1 MHz, respectively. The ferroelectric properties of these BNF nanotubes were demonstrated with a remnant polarization of 48 μC/cm^2 and a coercive electric field of 163 kV/cm.
