· JVASP-35944· LuS2

Lutetium disulfide (LuS₂) is a rare-earth transition metal dichalcogenide ceramic compound, part of the layered chalcogenide family that exhibits unique electronic and optical properties. While primarily a research material, LuS₂ and related lanthanide disulfides are investigated for applications in solid-state electronics, optoelectronics, and advanced energy storage systems where their layered crystal structure and rare-earth chemistry may offer advantages in device miniaturization and performance. Its potential lies in emerging technologies where conventional semiconductors or transparent ceramics are limited, though industrial adoption remains limited compared to established alternatives.

Regulatory Screening

Environmental

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.
