· GeSbO2S

GeSbO₂S is a chalcogenide glass ceramic composed of germanium, antimony, oxygen, and sulfur—a material class known for combining glass-forming properties with semiconducting or photonic functionality. This is primarily a research material studied for infrared (IR) optics, nonlinear optical applications, and potentially phase-change memory or sensing devices, where its mixed oxide-sulfide composition offers tunable refractive index and transparency in the IR spectrum.

Regulatory Screening

Environmental

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.
