title: The fabrication of La-substituted bismuth titanate nanofibers by electrospinning.
abstract: Bismuth titanates with La-substituted (Bi(3.25)La(0.75)Ti(3)O(12), BLT) nanofibers were synthesized by sol-gel based electrospinning. Pure phase perovskite structure BLT nanofibers could be obtained by annealing at 700 degrees C in air for 1 h. The morphology, crystallized phase and crystal structure were investigated by means of scanning electron microscopy, x-ray diffraction analysis and high resolution transmission electron microscopy, respectively. Nanofibers with fine crystallinity were observed with fiber diameters in the range of 100-300 nm and length over 150 microm. The ferroelectricity of BLT nanofibers has been confirmed by piezoresponse force microscopy. Excellent piezoelectricity of individual nanofibers has also been obtained.
