· JVASP-113061· Sm6Ge3Se14

Sm6Ge3Se14 is a rare-earth chalcogenide ceramic compound combining samarium, germanium, and selenium. This material belongs to the ternary rare-earth germanium selenide family, primarily of research interest for its potential optoelectronic and thermoelectric properties rather than established industrial production. The compound represents an emerging class of materials being investigated for mid-infrared photonic applications, solid-state lighting, and thermoelectric power generation in specialized temperature regimes.

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.
