| General description | Organically stabilized cadmium sulfide quantum dots in toluene. Kit contains six toluene solutions of CdS quantum dot nanocrystals with fluorescence emission maxima spanning UV-blue spectrum: • Lumidot™ CdS 380 5 ml, 5 mg/ml, 380 nm • Lumidot™ CdS 400 5 ml, 5 mg/ml, 400 nm • Lumidot™ CdS 420 5 ml, 5 mg/ml, 420 nm • Lumidot™ CdS 440 5 ml, 5 mg/ml, 440 nm • Lumidot™ CdS 460 5 ml, 5 mg/ml, 460 nm • Lumidot™ CdS 480 5 ml, 5 mg/ml, 480 nm · Lumidot™ CdS 380-480 nanocrystals are surface-stabilized with oleic acid coating. Typical nanocrystal sizes range from 1.6 nm (Lumidot™ CdS 380) to 7.3 nm (Lumidot™ CdS 480). The soft ligands increase hydrodynamic diameter of the nanocrystals by ~4.5-5 nm. |
