摘要：

Ferroelectric Bi3.25La0.75Ti3O12 (BLT) nanotubes were synthesized by sol-gel technique using nanochannel porous anodic aluminum oxide (AAO) templates, and were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and high resolution transmission electron microscopy (HRTEM). BLT nanotubes with diameter of around 240nm and the wall thickness of about 25nm exhibited a single orthorhombic perovskite structure and highly preferential crystal growth along the [117] orientation, which have smooth wall morphologies and well-defined diameters corresponding to the diameter of the applied template. The formation mechanism of BLT nanotubes was discussed. (C) 2011 Elsevier B.V. All rights reserved.
