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.

Applicazioni
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.
