Ce2S2O

Ce2S2O is an oxysulfide ceramic compound containing cerium, sulfur, and oxygen—a mixed-anion material that combines properties typical of both oxide and sulfide ceramics. This is a research-phase compound rather than an established industrial material; it belongs to the rare-earth oxysulfide family, which is of interest for optical, electronic, and thermal applications where conventional ceramics may be limited. The oxysulfide class is explored for luminescent materials, solid-state lighting components, and high-temperature structural applications, offering potential advantages in chemical stability and tunable electronic properties compared to simple oxides or sulfides alone.
