Structural and Optical Studies of Zinc doped BiFeO3 on the Bi-site

Abstract

Abstract Zinc-doped bismuth ferrite (Bi1-x Zn x FeO3, 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.
