| Hazard Information | Back Directory | [Description]
Thulium oxide (Tm2O3) powder has a greenish-white appearance. This rare earth sesquioxide has a cubic structure. The melting point of this material is approximately 2341°C. Tm2O3 is insoluble in water while it is slightly soluble in acidic environments. Tm2O3 has currently been receiving much attention because of its potential in the catalytic, electronic, optical and electrochemical applications. Tm2O3 has a high dielectric constant of 12–13 and its energy band gap of 5 eV. | [Chemical Properties]

| Questions and Answers (Q&A) | Back Directory | [Uses]
Thulium Oxide, also called Thulia, is the important dopant for silica-based fibre amplifiers, and also have specialized uses in ceramics, glass, phosphors, lasers. Because the wavelength of Thulium-based lasers is very efficient for superficial ablation of tissue, with minimal coagulation depth in air or in water. This makes Thulium lasers attractive for laser-based surgery.
