· Tb(InS2)3

Tb(InS2)3 is a rare-earth indium sulfide compound semiconductor composed of terbium and indium disulfide units, representing a niche material in the thiospinel or layered chalcogenide family. This is primarily a research compound rather than a mature industrial material, investigated for its potential optoelectronic and photovoltaic properties arising from the combination of rare-earth and transition-metal sulfide chemistry. Interest in this material class stems from tunable bandgaps, strong light-matter coupling, and the potential for next-generation thin-film photovoltaics, though practical device-level applications and manufacturing scale-up remain limited compared to conventional semiconductors.

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.
