Lanthanum manganite (LaMnO3) nanofibers were successfully fabricated by electrospinning utilizing sol-gel precursors. Polycrystalline cubic-perovskite structure LaMnO3 fibers of 50-100 nm were obtained by calcination of the inorganic/organic hybrid fibers at 600 degrees C for 1 h. The XRD results showed that the grain size of the fibers increased significantly with the increase of calcinations temperature. The average diameter of crystal grains was 17 nm after calcined at 400 degrees C for 2 h, then grew to 20 nm after heated up to 600 degrees C for 1 h. The morphology, microstructure, crystal structure and thermal analysis were investigated by SEM, TEM, XRD and TG-DSC, respectively. (c) 2007 Elsevier B.V. All rights reserved.
