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.
