Ge0.15Pb0.85Se0.85S0.15 is a quaternary lead chalcogenide semiconductor alloy combining germanium, lead, selenium, and sulfur in a solid-solution configuration. This material belongs to the narrow-bandgap semiconductor family and is primarily investigated for infrared (IR) optoelectronic applications, particularly in thermal imaging, infrared detection, and mid-to-far IR spectroscopy where its tunable bandgap and narrow energy gap provide sensitivity in wavelength ranges difficult to access with traditional semiconductors like silicon or gallium arsenide. The lead telluride/selenide/sulfide platform has been studied extensively in research contexts for thermoelectric and IR detector development, with the specific alloying composition here optimized to balance bandgap engineering with thermal stability and material processability.

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.
