Due to their exceptional structural and functional features, double perovskite materials have sparked considerable interest. This review focuses on the role of alkaline earth metals as doping elements in double perovskite compounds, examining their implications on structural and dielectric properties. The review begins with an explanation of the significance of double perovskite materials in the context of advanced materials research. It then looks into the synthesis methods used to integrate alkaline earth metals as dopants in the double perovskite lattice, clarifying their impact on crystal symmetry and stability. Advanced structural characterization techniques, like X-ray diffraction, electron microscopy, and spectroscopy, are addressed in order to highlight the structural changes caused by the doping process. the review also analyses the dielectric properties of alkaline earth metal-doped double perovskite materials, emphasizing the changes in electrical response and polarisation behaviour caused by the dopants. The link between dopant concentration, crystal structure, and dielectric performance is studied, providing useful insights for enhancing dielectric functions. The paper additionally analyses the numerous uses of double perovskite composites in photocatalysis, solar energy conversion, and electrical devices, highlighting the potential they hold as multifunctional materials. Finally, the importance of alkaline earth metal doping in altering the structural and dielectric properties of double perovskite materials is highlighted in this comprehensive analysis. It emphasizes the bright prospects of double perovskite composites even more, making it a significant resource for academics and scientists working on functional materials, energy conversion technologies, and advanced electronic applications. © 2024 Malaysian Institute of Chemistry.
