PbS (Lead Sulfide) pellets are a common material used for physical vapor deposition (PVD) techniques such as thermal and electron-beam evaporation to produce thin films. PbS is a narrow bandgap semiconductor with excellent infrared (IR) detection capabilities, making it highly useful in IR detectors, photovoltaics, and optoelectronic devices.
Key Applications:
- Infrared Detectors: PbS is widely used in IR sensors and detectors, particularly in the mid-infrared region (1-3 µm). It is sensitive to IR radiation, making it useful for applications like thermal imaging, spectroscopy, and gas sensing.
- Photovoltaics: PbS thin films are used in solar cells and photodetectors due to their strong light absorption and narrow bandgap properties, which allow efficient light-to-electricity conversion.
- Optoelectronics: PbS is utilized in optoelectronic devices such as infrared light-emitting diodes (LEDs) and lasers.
- Thermal Imaging: PbS coatings are applied in thermal imaging systems for military, aerospace, and industrial applications.
