Bi3.15Nd0.85Ti3O12 (BNT) nanofibers with radii in the range of 30–200 nm have been prepared by the electrospinning and sol-gel method, and the structure and morphology of the nanofibers were characterize by x-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Raman spectroscopy. The phase transition and piezoelectric characteristics of the BNT nanofibers were performed by thermal analysis and scanning probe microscopy, respectively. The BNT nanofiber exhibits an effective piezoelectric coefficient of 89 pm/V and a Curie temperature of 500 °C, which are higher than that of the BNT bulk.
