Description

NOM Blue & Blue/Green Quantum Dots provide narrow band fluorescent emission at wavelengths ranging from 420 nm to 520 nm. The Blue Quantum Dots have a CdS core and a ZnS shell while the Blue/Green quantum Dots have a CdSSe alloy core with a ZnS shell. These core/shell complexes provide higher levels of photoluminescence and stability when compared to core only complexes.Three different water soluble forms are coated with hydrophilic surfactants to achieve dispersion in water. The three different water soluble forms have surfactant terminal end groups that are either a carboxylic acid (-COOH), a primary amine (-NH2), or a diol (-CHOH-CH2OH). 

The following water soluble CuInZnS/ZnS core/shell Quantum Dots are in stock in the acid, amine, and diol coated forms.  Pricing begins at $299 for 10 mg.  Click links below to see specifications and spectra.
