What is Synthesis and optical characterization of Sr and Ti doped BiFeO~3~ multiferroics about?

## Abstract In this work, Sr and Ti doped BiFeO~3~ (bismuth ferrite) compositions with dopant x = 0.00 and x = 0.10 have been synthesized by conventional solid-state-reaction method. X-ray diffraction patterns of the pure and Sr and Ti modified BiFeO~3~ samples with x = 0.10 have shown single phase formation. Rietveld refinement of X-ray diffraction data for both the samples has revealed Rhombohedral structural symmetry with R3c space group. Fourier-transform infrared spectroscopy spectra, recorded in the range 1000–400 cm^−1^ show shift in the position of a broad hump at higher wave number side with x which may be attributed to the stretching of Bi–O and Fe–O bonds due to doping. UV–visible spectra (ultraviolet-visible spectroscopy) in the range 300–800 nm have revealed a slight increase in the band gap with substitution.
