· Na2In4Se6S

Na2In4Se6S is a mixed-anion semiconductor compound containing sodium, indium, selenium, and sulfur elements, belonging to the family of chalcogenide semiconductors with layered or complex crystal structures. This material is primarily of research and developmental interest for optoelectronic and photovoltaic applications, where the tunable bandgap and mixed-anion composition offer potential advantages over binary or ternary semiconductors for light absorption and charge transport. The substitution of sulfur into indium selenide frameworks is investigated as a method to engineer band structure and thermal stability for next-generation thin-film solar cells, photodetectors, and potentially nonlinear optical 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.
