Lead Sulfide (PbS) Quantum Dots emit and absorb lights in the near-infrared (NIR) range from 800 to 2000 nm depending on nanoparticle sizes from 2.7 to 9 nm respectively. PbS quantum dots are suitable for the use as light absorber or IR emitter in such applications as solar cells, photodetectors and infrared LEDs

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

PbS Quantum Dots main features:

  • Wide products range 900-1600 nm of emission and 800- 2000 nm of absorption peaks.
  • Narrow emission and absorption fluorescence bands (FWHM) due to narrow particle size distributions that results in higher devices performance (in solar cells, sensors, LEDs).
  • High crystallinity with high peak-to-valley ratios
