PbS Quantum Dots (Lead Sulfide) absorb the light through all visible and near-infrared (NIR) range and re-emit in NIR range from 800 to 2000 nm depending on nanoparticle sizes from 2.5 to 9 nm respectively. PbS quantum dots are suitable for the use as light absorber or NIR emitter in such applications as solar cells, photodetectors and infrared LEDs.

QUANTUM SOLUTIONS offers PbS Quantum Dots with different absorption profiles (that is characterized with the first excitonic peak absorption from 800 to 2000 nm) and different emission peaks (from 900 to 1600 nm).

PbS QDs are 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 or toluene) are also available.

QUANTUM SOLUTIONS is the developer and large scale manufacturer of PbS quantum dots according to customers requirements and interested in partnerships for industrial product development. Also you can order quantum dots for research purposes.

This product is also found on Merk/Millipore Sigma.

PbS Quantum Dots Applications

PbS Quantum Dots main features:

  • PbS QDs with different absorption profiles (that is characterized with the first excitonic peak absorption from 800 to 2000 nm) and emission peaks (from 900 to 1600 nm)
  • Narrow emission and absorption fluorescence bands (FWHM) due to narrow particle size distributions that results in higher devices performance (in solar cells, photodetectors, NIR LEDs).
  • High crystallinity with high peak-to-valley ratios
