Contents

The vial(s) contains CdSxSe1-x/ZnS core/shell fluorescent nanocrystals with alkyl ligand surface.

Features


  • Unlike traditional quantum dots, emission wavelength is tunable by composition rather than size.
  • Proprietary surface passivation and ligand technology isolates the core from oxygen and harmful ions that can degrade quantum dot performance over time.
  • Photostable (no bleaching)
  • Narrow and sharp emission peaks
  • All colors equally bright
  • Comparable quantum efficiencies (50%) throughout the visible spectrum
  • Semiconductor Grade
  • pH Neutral

Storage & Stability

The nanocrystals should be stored in the dark at 4oC. The shelf life is approximately one year under these conditions.

Nanocrystals may be isolated by using a polar solvent/nonpolar solvent precipitation method. Normally, methanol is used as the polar solvent.
 
Nanocrystals will begin to precipitate at 30-40% methanol in toluene. Additional surface modification is necessary to impart water solubility.
