Strontium tungsten oxide is primarily used in the field of materials science, particularly in the development of advanced ceramics and phosphors. Its unique properties make it suitable for applications in solid oxide fuel cells (SOFCs), where it serves as an electrolyte or electrode material due to its high ionic conductivity and stability at elevated temperatures. Additionally, it is utilized in the production of luminescent materials, where it acts as a host matrix for doping with rare earth elements to create phosphors for lighting and display technologies. The compound is also explored in photocatalysis for environmental remediation, leveraging its ability to facilitate chemical reactions under light irradiation.
