Nd2O3
semiconductor· Nd2O3
Nd₂O₃ (neodymium oxide) is a rare-earth ceramic compound belonging to the lanthanide oxide family, valued primarily for its optical and electronic properties rather than structural applications. It is used in phosphors for display technologies, optical coatings, and as a dopant in laser materials and fiber-optic amplifiers, where it enables efficient light emission and signal amplification. Engineers select Nd₂O₃ over alternative rare-earth oxides when near-infrared emission (particularly around 1.06 µm) or specific refractive index characteristics are required; it is also investigated in nuclear fuel additives and advanced ceramics for specialized high-temperature or radiation environments.

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.
