· Ca2 Ag2 O4

Ca₂Ag₂O₄ is a mixed-valence oxide semiconductor combining calcium and silver in a layered crystalline structure, belonging to the family of ternary metal oxides with potential photocatalytic and optoelectronic properties. This is primarily a research-phase compound explored for photocatalysis, antimicrobial coatings, and next-generation photovoltaic applications due to silver's known plasmonic properties and the stability of the calcium-silver oxide framework. Its use remains largely experimental compared to established semiconductors like TiO₂ or ZnO, making it relevant to advanced materials developers and researchers seeking alternative compositions for environmental remediation or biomedical device surfaces.
