Our improved PbS/CdS Near infrared (NIR) Quantum Dots range in narrow band fluorescent emission wavelengths from 900 nm to 1000 nm. These core/shell Quantum Dots have higher quantum yields (are brighter) and have greater wavelength stability relative to the core only PbS quantum dots that are commercially available. These core/shell quantum dots are surface coated with organic surfactants that make them lipophilic and soluble in organic solvents such as toluene, chloroform, and heptane. All emission center wavelengths in the range of 900 nm to 1000 nm, ±10 nm, are available from inventory. These QDs extend the long wavelength range of near infrared fluorescence out to 1000 nm. Water soluble PbS/CdS core/shell Quantum Dots are also available.
Prices for organic soluble QDs start at $195 for 10 mg (minimum order); Available from inventory in quantities of 10 , 25, 50 and 100 mg. Evaluation kits containing any three emission wavelengths of longer infrared, organic soluble PbS/CdS Quantum Dots are also available at $495 for 10 mg of each wavelength.
