Ho4 Se4 O12 F4

Ho₄Se₄O₁₂F₄ is a rare-earth oxyselenide fluoride ceramic combining holmium (a lanthanide), selenium, oxygen, and fluorine into a mixed-anion structure. This is a research-phase compound typical of synthetic rare-earth ceramics designed for specialized optical, electronic, or thermal applications where multiple anion frameworks provide tunable properties. Such fluoride-oxide hybrids are investigated for photonic devices, thermal management systems, and solid-state chemistry platforms where traditional single-anion ceramics fall short.
