· Ag0.5Ge1Pb1.75Se4

Ag0.5Ge1Pb1.75Se4 is a mixed-cation chalcogenide semiconductor belonging to the IV–VI semiconductor family, combining silver, germanium, lead, and selenium in a layered or amorphous structure. This is a research-grade compound designed for infrared optics and thermal imaging applications, where its wide bandgap and high refractive index in the mid- to long-wave infrared region make it a candidate alternative to traditional chalcogenide glasses. The material remains largely experimental; it represents a class of multinary chalcogenides being investigated for improved transparency, thermal stability, and resistance to crystallization compared to simpler binary or ternary chalcogenides, making it relevant for next-generation thermal sensors and infrared window applications.

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.
