Lu2O3
semiconductor· Lu2O3
Lutetium oxide (Lu₂O₃) is a rare-earth ceramic oxide semiconductor with a high refractive index and wide bandgap, belonging to the lanthanide oxide family. It is primarily used in advanced optics, scintillation detectors for high-energy physics and medical imaging, and as a host material for laser-active ions in solid-state lasers. Lu₂O₃ is valued in these specialized applications for its excellent optical transparency in the UV-visible-infrared range, high chemical stability, and superior performance compared to more common rare-earth alternatives like Y₂O₃, though its cost and limited availability restrict use to applications where performance justifies the premium.

Regulatory Screening
Environmental
Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
