Overview
Description

Our PbS/CdS quantum dots use PbS as the core, CdS as the shell, and the surface is coated with hydrophobic ligands, making them lipophilic and soluble in organic solvents such as toluene, chloroform, and heptane. Their narrow-band fluorescence emission wavelengths range from 900 nm to 1000 nm. Due to their efficient emission in the infrared spectral range, they have great potential for applications ranging from tunable infrared lasers to solar cells.
