· Ba2ErGaSe5

Ba₂ErGaSe₅ is a quaternary chalcogenide semiconductor compound combining barium, erbium, gallium, and selenium in a fixed stoichiometric ratio. This material belongs to the family of rare-earth-containing selenide semiconductors, which are primarily investigated in research settings for their potential infrared optoelectronic and photonic applications. The incorporation of erbium—a lanthanide element—positions this compound as a candidate material for mid-infrared emission and nonlinear optical devices, though it remains largely in the exploratory phase rather than established commercial production.

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.
