QDot™ PbS Quantum Dots absorb the light through UV-Visible up to near-infrared (NIR) range and re-emit in NIR range. The absorption/emission profiles can be tuned from 700 to 2000 nm simply by changing nanoparticle sizes from 2 to 10 nm. This materials has outstanding light absorption and photoelectric properties and suitable for such optoelectronic applications as near-infrared image sensors, solar cells and infrared LEDs. For specific application convenience, two lines of QDs are available:

  • With specific absorption peak in 700 – 2000 nm range
  • With specific emission peaks in 900 – 1600 nm range

QDot™ 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.

QDot™ PbS Quantum Dots Applications

QDot™ PbS Quantum Dots main features:

  • Unprecedented control of absorption/emission peaks (up to ±5 nm)
  • Devices grade QDs with high crystallinity (high peak-to-valley ratios), purity and surface cleanness
  • Narrow particle size distribution (FWHM of absorption and emission < 100-120 nm) for higher devices performance
  • Superior optical properties with intense absorption and emission
