The stokes shift for this material is expected to be around 30 nm. If the batch has an excitonic absorption peak at 1540 nm, the photoluminescence peak can be expected to be at 1570 nm. In terms of the photoluminescence quantum yield, a value between 25 to 30% PLQY is anticipated. Additionally, a photoluminescence (PL) spectra is provided, where the solid line represents the absorption spectra, and the dashed line represents the PL spectra.

Aplicação
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.

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
Artigos
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.
