Synthesis and Characterization of Flower-like Clewed PbTiO_3 Nanowires Prepared by Hydrothermal Method

摘要

Flower-like clewed PbTiO_3 (PT) nanowires have been synthesized using hydrothermal method. The nanowire have an average length of 0.5μm and a mean diameter of 10-20 nm, the clews have average diameters of 1μm. With tetragonal lattice structure, the clewed PT nanowire grow along the (001) direction. The growth mechanism has been discussed. To fabricate nanowire-clew, the reaction temperature and the nonpolar surfactant are proved to be critical factors.
