· Ho4 Te4 Cl4 O12

Ho₄Te₄Cl₄O₁₂ is a rare-earth transition metal halide-tellurite compound that belongs to the family of mixed-anion semiconductors combining holmium, tellurium, chlorine, and oxygen. This material is primarily of research interest rather than established industrial use, studied for its potential in optoelectronic and photonic applications due to the optical properties imparted by holmium lanthanide ions and the semiconducting behavior of the tellurite-halide framework. The compound represents an experimental platform for investigating how multi-anion coordination in rare-earth systems can engineer band gaps and carrier dynamics for next-generation electronic or photonic devices.
