采用水热法首次合成了Bi3.15Nd0.85Ti3O12（BNT）纳米棒。纳米棒沿其长度方向沿着是均匀的，并且由具有正交结构的单晶BNT组成。BNT纳米棒的直径约为30- 120 nm，沿[104]方向沿着生长，有望成为纳米级铁电传感器的候选材料。正交相BNT纳米棒的10个拉曼激活模式被观察到，这是过阻尼和高度移动相比，Bi 4 Ti 3 O 12（BIT）粉末。样品的化学组成和元素的价态由X射线光电子能谱测定。
Bi3.15Nd0.85Ti3O12(BNT) nanorods were successfully synthesized first time by hydrothermal method. The nanorods are uniform along their length, and are composed of single-crystalline BNT with orthorhombic structure. The diameters of BNT nanorods are about 30–120nm and growth along the [104] direction, which are promising candidate for nanoscale ferroelectric sensors. Ten Raman active modes were observed for orthorhombic phase BNT nanorods, which are overdamped and highly shifted compare to that of Bi4Ti3O12(BIT) powders. The chemical composition of the samples and the valence states of elements were determined by X-ray photoelectron spectroscopy.
