Synthesis, structural and optical properties of lead titanate nanorods by electrospinning

Abstract

Abstract Lead titanate (PbTiO 3 ) nanorods with diameters ranging between 300 and 450 nm were synthesized using a combination of the electrospinning and calcination processes. The XRD patterns showed that the crystalline phases were in good agreement with tetragonal PbTiO 3 . Crystallite size, lattice parameters, cell volume, tetragonality, and X-ray densities increased with increasing calcination. SEM and TEM images revealed the morphology of the PbTiO 3 nanorods as rough with combined nanograins varying in size between 70 and 130 nm. The band gap energy of PbTiO 3 was determined to be in the range of 2.82-2.86 eV, demonstrating that calcination influenced the crystallinity, morphology, and band gap energy of the PbTiO 3 nanorods.
