Application

Lead sulfide quantum dots are inorganic semiconductors with an outer surface coating of organic ligands. Due to their excellent photosensitivity and band-gap tunability, they find applications in photodetectors. These particles are tuned to 1550 nm and are compatible with standard silicon-based complementary metal-oxide semiconductor (CMOS) read-out circuits.

Other applications of these materials include light detection and ranging (LIDAR), 3D laser scanning, solar cells, as well as Time of Flight (ToF) sensing.

Infrared Lead Sulfide Quantum Dots: Properties and Applications

Infrared lead sulfide (PbS)-based quantum dots absorb and emit light across the near-infrared and short-wave infrared wavelengths. Our PbS quantum dots have well-characterized optoelectronic properties and surface chemistry suitable for integration into photodetectors, photovoltaics, and infrared LEDs.
