Overview
Description

Our cadmium-based near-infrared quantum dots have narrow-band fluorescence emission wavelengths ranging from 700 nm to 880 nm, which can provide higher levels of photoluminescence and stability. These NIR quantum dots are coated with organic surfactants, making them lipophilic and soluble in solvents such as toluene, chloroform and hexane. One such application is for near-infrared camera imaging.
