· Pb0.95Ge0.05Se

Pb0.95Ge0.05Se is a lead-germanium-selenium compound semiconductor, a narrow-bandgap material derived from lead selenide (PbSe) with small germanium substitution to engineer its electronic properties. This material is primarily investigated for infrared detection and thermal imaging applications, where its bandgap makes it sensitive to mid-to-long wavelength infrared radiation; the germanium doping allows fine-tuning of the bandgap and carrier properties compared to pure PbSe. Lead chalcogenide semiconductors like this are valued in defense, medical diagnostics, and scientific instrumentation where sensitivity in the 2–5 μm infrared region is critical, though this particular composition remains largely a research material used to optimize performance-cost tradeoffs in detector design.

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.
