Cs₂Se₃ is a ternary ionic ceramic compound composed of cesium and selenium, belonging to the family of chalcogenide ceramics. This material is primarily of research interest rather than established in high-volume commercial applications; it is studied for its potential in solid-state ionics, photovoltaic devices, and radiation detection systems, where cesium compounds are valued for their response to high-energy particles and optical properties.
