Exposition of structural, microstructural and optical properties of Mg and Zr doped BiFeO3 for profound optoelectronic device applications

ABSTRACTMagnesium (Mg) and zirconium (Zr) doped bismuth ferrite (BiFeO3; BFO) ceramics such as Bi1−xMgxFeO3 (Mg doped BFO; BMO), BiFe1−xZrxO3 (Zr doped BFO; BZO) and Bi1−xMgxFe1−xZrxO3 (both Mg and Zr doped BFO; BMZO) with x = 0 and 0.1 were synthesized by solid-state reaction techniques. The distorted rhombohedral structures of doped BFO were confirmed by X-ray diffraction analysis. The microstructural analysis revealed that there were uniform dispersions and homogeneous distributions of ceramics in BMZO as compared to BMO, BZO and plane BFO. The optical properties signified that BMZO having the lowest optical band gap had profound optical performance in optoelectronic device applications than that of BMO, BZO and plane BFO.
