## Description

- description: 'This study investigates the chemical synthesis of trivalent iron cation
    Fe3+ substituted α-phase alumina, α-Al2O3:Fe3+. α-Al2O3:Fe3+ samples were synthesized
    from α-Al2O3 and α-Fe2O3 powders within the composition range of Al2-xFexO3 (x=0.02-0.04).
    X-ray diffraction (XRD) analysis confirmed that the synthesized samples were in
    α-phase crystalline structure. UV–Vis absorption spectroscopy revealed that the
    predominant oxidation state of iron cations substituting Al3+ sites in α-Al2O3
    is Fe3+. Fourier-transform infrared (FTIR) and Raman scattering spectroscopy were
    employed to examine the lattice dynamics of the α-Al2O3:Fe3+ samples. '
