· PbSe0.9S0.1

PbSe₀.₉S₀.₁ is a lead chalcogenide alloy—a solid solution of lead selenide and lead sulfide—belonging to the IV-VI narrow-bandgap semiconductor family. This mixed-anion compound is primarily investigated for infrared (IR) detection and thermal imaging applications, where partial sulfide substitution in the lead selenide matrix enables tuning of the bandgap and lattice parameters to optimize performance in specific wavelength windows. The material sits between bulk PbSe (mid-IR sensitive) and PbS (near-IR sensitive), making it particularly relevant for aerospace and military thermal sensing systems where spectral selectivity and temperature stability are critical.
