Pb₁Se₀.₉S₀.₁ is a ternary lead chalcogenide semiconductor formed by alloying lead selenide (PbSe) with a small fraction of lead sulfide (PbS). This mixed-anion compound belongs to the narrow-bandgap semiconductor family and is primarily of research and specialized industrial interest for infrared applications where tuning the bandgap between PbSe and PbS compositions offers performance advantages. The material is used in infrared detectors and thermal imaging systems where its narrow bandgap enables sensitivity in the mid- to far-infrared spectrum, and the sulfide doping modulates optical and electronic properties compared to pure PbSe.
