Overview

Description

CdSe/ZnS Quantum Dots are produced by a special patented process, which has the advantages of small half-peak width of emission spectrum, high luminous efficiency and stable performance. Our CdSe/ZnS core/shell complexes provide narrow-band fluorescence emission in the wavelength range from 540 nm to 680 nm with higher levels of photoluminescence and stability. Our quantum dots are coated with organic surfactants, making them lipophilic and soluble in organic solvents such as toluene, chloroform, and​hexane.
