CdTe QDs

CdTe Quantum Dots, hydrophilic

Easily form colloidal solutions in water. Terminated with -COOH group. Supplied as a powder readily soluble in water. Ideal for labelling purposes. Coupling with -NH2 groups can be achieved through EDC-mediated esterification.
Emission peak width: 30-100 nm (depending on the emission wavelength)
Stokes shift to the first exciton: 10-20 nm
Typical quantum yield: 15-90 %(depending on the emission wavelength)
