abstract = "The Bi 1-xLa xFe 1-yMg yO 3 thin films were fabricated on Si (100) by sol-gel method. X-ray diffraction analysis shows that all the films are perovskite structure with space group R 3C with x and y range from 0 to 0.1 altogether. Moreover, the co-doped La and Mg distorted BiFeO 3 lattice structure which induced from Raman study. The refractive index n and extinction coefficient k of the co-doped BiFeO 3 film obviously get larger with the La and Mg concentration, and the band-gap energy of BiFeO 3 was found to be 2.45±0.02ev and that of Bi 0.95 La 0.05 Fe 0.95 Mg 0.05 O 3 and Bi 0.9 La 0.1 Fe 0.9 Mg 0.1 O 3 were 2.40±0.02ev and 2.35±0.02ev, respectively. Our results suggest that small amount of La and Mg doping can change optical property of BiFeO 3 material.",
