QDot™ PbS Quantum Dots have the following advantages:

Optoelectronic device grade QDs to be used in near-infrared (NIR) or short-wave infrared (SWIR) image sensors
Unprecedented absorption/emission peaks accuracy and reproducibility (up to +/-5 nm)
Narrow particle size distribution (FWHM of absorption and emission < 100-120 nm, STDV < 5-10%) for higher devices performance

QDot™ PbS QDs selection guidance
QDot™ PbS Quantum Dots have a broad absorption profile, from high energy photons up to NIR light.

Looking closer in the NIR range reveals that QDs can be categorised according to their absorption profile (red line “Absorption”) or emission profile (purple line “Emission). Absorption profile is categorised according to the first excitonic absorption peak, the absorption FWHM and the peak-to-valley ratio. Emission profile is characterised by emission peak, emission FWHM and PLQY. The difference between the first excitonic absorption peak and emission peal is called a stokes shift. Follow Table 1 to choose QDot™ materials based on absorption (abs) parameters, and Table 2 to choose QDot™ materials based on emission (em) parameters. QDot™ PbS QDs can be supplied as a solid paste/powder that is easily soluble in octane or any other non-polar solvents (hexane, toluene, chloroform, chlorobenzene, dichlorobenzene) in a wide range of concentration up to 100-150 mg/mL. PbS QDs in a solution form (octane, toluene or other non-polar solvents) are also available.
