【 摘 要 】

Zinc-doped bismuth ferrite (Bi1-xZnxFeO3, x = 0, 0.05, 0.1) powdered were synthesized through sol-gel auto combustion methods to investigate the optical properties while maintaining the whole structure of BiFeO3 (BFO). The Zn doped induced the reveal of Bi25FeO40 as a secondary phase and decreased the bond angle of Bi-O-Fe in the BFO phase structure which affect the electron density formation inside of the lattice. The presence of Zn content has also conducted the shifting of optical absorption in the UV-Vis region and increasing the dielectric constant value. This property is potent in visible light photonic applications.
