Effect of Synthesis Techniques on Bismuth Ferrite (BiFeO₃) — An Investigative Study Using Structural, Optical, and Electrochemical Performance Towards Photostability

The interest in BiFeO₃ perovskite for photostable applications is rapidly rising, owing to its efficient single photon emitter behavior. A detailed analysis of the structural, optical and electrochemical behavior of BiFeO₃ perovskite synthesized by different synthesis techniques viz. sol–gel and solid-state synthesis techniques, divulging that 30–40-nm-sized-prepared BiFeO₃ have well-grown grains but the grain size is non-uniform. The major problem faced in these materials is their photostability under optical excitation. Sol–gel-assisted synthesis procedure exhibited enhanced photostability. Remarkable magnetic and impedance properties of the synthesized material satisfy the competitiveness and also pave a way for the development of perovskite photovoltaics. Hence, the enhancement in the magnetic and impedance properties of BiFeO₃ clearly focuses on the importance of sintering atmosphere and also paves a way for BFO thin film for applications in optoelectronics.
