BiFeO 3 is one of the multiferroic materials and have a wide range of application. For that reason, pure BiFeO3 (BFO), Li and Zn doped BFO were synthesized by sol-gel method. Structure and optical properties of BiFeO 3 were characterized by using X-ray diffractometer and UV-Vis spectrophotometer. Pure BiFeO3 and single phase Li-doped BiFeO 3 were detected from XRD pattern. Two-phase were identified in Zn doped BiFeO 3 . The Structure parameters of the three samples seem altered. Doping Li and Zn decrease crystal parameter. The Energy gap was calculated from the UV-Vis absorbance pattern, and pure BiFeO 3 , Li and Zn doped BiFeO 3 have energy gaps 2.81, 3.19 and 4.82 eV respectively. The decrease of crystallite structure caused by the doping would raise the band gap energy.
