· Ag0.5Ge1Pb1.75S4

Ag0.5Ge1Pb1.75S4 is a quaternary chalcogenide semiconductor compound combining silver, germanium, lead, and sulfur in a mixed-cation sulfide structure. This material belongs to the family of complex sulfide semiconductors, which are primarily investigated for infrared optics, nonlinear optical applications, and solid-state radiation detection due to their wide bandgap tunability and strong light-matter interactions in the mid- to far-infrared spectrum. The specific Ag-Ge-Pb-S composition is largely experimental and of research interest rather than established in high-volume industrial production; it represents an effort to optimize bandgap and optical properties by combining multiple cation sites that independently contribute to electronic structure.

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.
