Lutetium Oxide (Lu2O3) Powder
Lutetium oxide (Lu2O3), also known as lutecia, has a cubic crystal structure and available in white powder form. This rare earth metal oxide exhibits favorable physical properties, such as a high melting point (around 2400°C), phase stability, mechanical strength, hardness, thermal conductivity, and low thermal expansion. The compound is also known to have a wide bandgap of 5.2–5.5 eV and a high-κ dielectric constant of about κ = 11–13. The high density of Lu2O3 is utilized in scintillators and in various activators due to its wide bandgap. Due to its excellent physical properties lutetium oxide is considered to be an excellent phosphor host material. Rare earth compounds such as Pr, Sm, Eu, Tb, Dy, Ho, Er, Tm are frequently used as dopants in lutetium oxide structure. Such compounds provide important phosphors and high-power lasers. Furthermore, Lu2O3 can be used as additives in glass and ceramics, as a catalyst for hydrogenation, polymerization, cracking, and alkylation reactions.
