· Tb4 Se2 O4

Tb4Se2O4 is a rare-earth mixed-valence oxide-selenide semiconductor combining terbium, selenium, and oxygen in a layered or complex crystal structure. This is a specialized research compound rather than a production material; it belongs to the rare-earth chalcogenide family and is of interest for its potential optoelectronic and magnetic properties arising from the 4f electrons of terbium.

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.
