Recent Advances in Eu-Doped LaFeO₃ Perovskite Oxides: Structure–Property Relationships and Applications

Abstract

Europium-doped Lanthanum Ferrite (La₁₋ₓEuₓFeO₃) perovskite oxides have attracted significant interest due to their adjustable structural distortion, magnetic modulation, enhanced dielectric response, and promising catalytic and sensing functionalities. This review provides a comprehensive analysis of recent developments in synthesis methods, phase evolution, structural modifications, and the resultant impacts on physical properties. Detailed correlations between Eu content, crystallographic changes, electronic structure, and multifunctional performance in catalytic, dielectric, and energy-related applications are emphasized. The paper concludes with critical challenges and future research directions necessary for advancing this class of materials toward practical applications.
