Used primarily in research and specialty applications, this compound serves as a precursor for synthesizing other thulium-containing materials. It is employed in the preparation of thulium oxide, which finds use in high-temperature superconductors and ceramic materials. Due to thulium’s strong luminescent properties, derivatives made from this compound are explored in optoelectronic devices and phosphors for display technologies. Additionally, it plays a role in doping crystals for solid-state lasers operating in the near-infrared range. Its use in medical imaging and radiation detection is under investigation owing to thulium's favorable emission characteristics. The compound also supports studies in coordination chemistry and lanthanide separation processes.
