Lu2 O3

Lu₂O₃ is a rare-earth oxide ceramic composed of lutetium and oxygen, belonging to the family of lanthanide oxides used in advanced technical applications. It is employed in specialized high-temperature optics, scintillator materials for radiation detection, and as a host material for laser-active dopants in solid-state lasers. Engineers select Lu₂O₃ when extreme thermal stability, high refractive index, and radiation hardness are critical, particularly in nuclear instrumentation, medical imaging, and next-generation photonic devices where common ceramics would degrade.
