Structure and electrical properties of Bi3.15Nd0.85Ti3O12 nanofibers synthesized by electrospinning and sol-gel method

摘要

Bi3.15Nd0.85Ti3O12 u0001BNTu0002 nanofibers with radii in the range of 30–200 nm have been prepared by thenelectrospinning and sol-gel method, and the structure and morphology of the nanofibers werencharacterize by x-ray diffraction, scanning electron microscopy, transmission electron microscopy,nand Raman spectroscopy. The phase transition and piezoelectric characteristics of the BNTnnanofibers were performed by thermal analysis and scanning probe microscopy, respectively. ThenBNT nanofiber exhibits an effective piezoelectric coefficient of 89 pm/V and a Curie temperature ofn500 °C, which are higher than that of the BNT bulk. © 2010 American Institute of Physics.nu0003doi:10.1063/1.3276688
