· ScAg(PSe3)2

ScAg(PSe3)2 is an experimental ternary chalcogenide semiconductor composed of scandium, silver, and phosphorus selenide units, representing a rare combination of elements in the phosphorus selenide family. This material is primarily of research interest for solid-state physics and materials discovery rather than established industrial production, with potential applications in thermoelectric devices, photovoltaic absorbers, or ion-conducting phases due to the presence of mobile silver cations. The scandium-silver-selenide framework is notable for combining rare-earth and post-transition metal chemistry in ways that may enable tunable electronic or ionic properties unavailable in more 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.
