Structural characterization of iron titanium oxide synthesized by sol–gel spin-coating technique

For the first time, crack-free, dense and transparent polycrystalline orthorhombic Fe 2TiO 5 single-phase structure thin films have been prepared by a sol–gel method using titanium isopropoxide and iron oxalate. The formation of the Fe 2TiO 5 phase started from 400°C onwards. No cracks, formation of...

Description
Summary:For the first time, crack-free, dense and transparent polycrystalline orthorhombic Fe 2TiO 5 single-phase structure thin films have been prepared by a sol–gel method using titanium isopropoxide and iron oxalate. The formation of the Fe 2TiO 5 phase started from 400°C onwards. No cracks, formation of other phases or diffusion of Si was observed even after application of the annealing temperature of 800°C for 5 h. The structural, morphological and elemental evolution of these Fe 2TiO 5 thin films produced by the sol–gel synthesis were characterized by Grazing Incidence X-ray Diffraction (GIXRD), Tapping Mode Atomic Force Microscopy (TMAFM), and X-ray Photoelectron Spectroscopy (XPS), respectively.
