· JVASP-143164· LuSeF

LuSeF is a rare-earth selenide fluoride ceramic compound containing lutetium, selenium, and fluorine. This material represents an emerging class of mixed-anion ceramics being investigated for their unique crystal structures and potential functional properties at the intersection of ionic and covalent bonding. While primarily in the research phase, selenide fluorides are of interest for high-temperature applications, optical devices, and solid-state chemistry studies where conventional oxides or single-anion systems are insufficient.
