· Tb4GaSbS9

Tb4GaSbS9 is a rare-earth mixed-metal sulfide compound combining terbium, gallium, and antimony in a sulfide lattice—a quaternary chalcogenide semiconductor belonging to the family of rare-earth thiospinels and related sulfide structures. This is a research-phase material studied primarily for its optoelectronic and photonic properties; while not yet in widespread industrial production, compounds in this family are investigated for applications requiring wide bandgaps, strong photoluminescence, or specialized optical functionality in solid-state devices.

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.
