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 for biological applications.
