· Yb2 O4

Ytterbium oxide (Yb₂O₃) is a rare-earth ceramic semiconductor belonging to the lanthanide oxide family, characterized by high thermal stability and optical transparency in specific wavelength ranges. While primarily investigated in research contexts for photonic and optoelectronic applications, it is used industrially as a dopant in laser crystals (particularly for fiber lasers), phosphors for display technologies, and as a refractory material in high-temperature applications where chemical inertness and thermal shock resistance are critical.

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.
