Fluorescent Nanocrystals Alkyl Modified
Nanodiagnostics organic soluble semiconductor CdSSe/ZnS core/shell quantum dots (fluorescent nanocrystals) are functionalized with a small alkyl ligand and are available with emissions from 450nm-665nm.
In comparison to traditional quantum dots, Nanodiagnostics Fluorescent Nanocrystals are tuned by composition rather than size resulting in all particles having the same diameter (5.5nm-6.5nm) regardless of emission wavelength.
These fluorescent nanoparticles are ideal for use in applications e.g. nanoelectronics and opto-electronics or we can use for further functionalization with various polymers and ligands.
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.
Features
Storage & Stability
The nanocrystals should be stored in the dark at 4oC. The shelf life is approximately one year under these conditions.
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
