Tailoring structural and optical properties of LaGaO3 perovskite through strontium (sr) substitution: Insights and applications

Abstract

In this groundbreaking research, we investigate the nuanced impact of controlled strontium (Sr) substitution on LaGaO3 perovskite, specifically exploring La1-xSrxGaO3 (x = 0; 0.1; 0.2) composites. Through meticulous synthesis and detailed characterization using X-ray diffraction, UV–Visible diffuse reflectance spectroscopy (UV–Vis DRS), and Photoluminescence Spectroscopy (PL), our study unravels the intricacies of dopant-induced modifications. The X-ray diffraction (XRD) analysis reveals the emergence of secondary phases, shedding light on the structural modifications induced by Sr2+ substitution. UV–Vis DRS measurements show shifts in band gaps, indicative of changes in the optical properties of the composites. The results Photoluminescence Spectroscopy illuminated the intricate spectral changes induced by dopants, offering insights into the interactions between impurity ions and color centers. This work not only advances our fundamental understanding of the complex relationship between dopants and perovskite materials but also highlights the potential applications of these composites. The ability to engineer both structural and optical properties through controlled Sr2+ substitution holds promise for innovations in optoelectronics, catalysis, and beyond. As materials science continues to push the boundaries of interdisciplinary research, this study contributes to the evolving landscape of advanced materials with tailored properties for emerging technologies.
