The effect of calcination temperature (500°, 600° and 700°C) on structural properties of BiFeO3 synthesized by sol-gel method was studied. The structure of BiFeO3 sample was investigated by using X-ray diffraction (XRD), Raman scattering spectroscopy, Fourier Transform Infrared spectroscopy (FTIR), and supported by UV-Visible spectrophotometry (UV-Vis) analysis. The XRD analysis revealed the stability of single-phase hexagonal crystal structure with R3c space group in calcination condition of 700°C. The Raman spectroscopy observed the presence of Fe-O stretching which is also confirmed by FTIR analysis. UV-Vis measurement described the slightly increasing of gap energy as calcination temperature increase.
