Abstract Bi{sub 1-x}Pr{sub x}Fe{sub 1-x}Ti{sub x}O{sub 3} ceramics with x = 0.00, 0.10 and 0.20 were synthesized by solid state reaction method. Rietveld fitting of diffraction data reveals structural transition from rhombohedral phase (R{sub 3C}) for x ≤ 0.10 to orthorhombic phase (P{sub nma}) for x = 0.20. FTIR spectra exhibit broad absorption bands, which may be due to the overlapping of Fe-O and Bi-O vibrations in these ceramics. UV-visible spectroscopy results show strong absorption of light in the spectral range of 400-600 nm, indicating optical band gap in the visible region for these samples.
