Anwendung
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 1350 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.

PbS quantum-dot-doped glasses are demonstrated as saturable absorber Q-switches for 2 microm holmium lasers. Q-switched pulses from Ho3+:Y3Sc2Al3O12 and Ho3+:Y3Al5O12 lasers of 50 and 70 ns in duration, respectively, have been obtained demonstrating up to 13% of energy conversion efficiency

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.
