Abstract

The electronic and crystalline properties of iron-inserted titania (Fe_xTi_1−xO₂) nanoparticles were measured using synchrotron-based soft X-ray spectroscopy and high-temperature X-ray powder diffraction (HT-XRD). The data from X-ray absorption and emission spectroscopy were used to examine occupied and unoccupied densities of states for O 2p and Ti/Fe 3d hybrid orbital characteristics. It was found that Fe³⁺ insertion resulted in an up-shift of the band gap from 3.20 to 3.46 eV. This observation reflected site occupancy in the TiO₂ lattice by Fe dopant ions. From HT-XRD Rietveld analysis, Ti occupancy was found to be 0.92 and oxygen 1.00. In addition, the crystal structure remained anatase within a temperature range of 25–800 °C, while the lattice distortion increased due to thermal expansion.
