Design of cadmium-free colloidal II–VI semiconductor quantum dots

QDs that exhibited red, green and blue emission were explored to develop cadmium-free II–VI chalcogenide-based QD-phosphors. We considered that highly monodisperse colloidal QDs with diameters of 3–6 nm are easy to synthesize and II–VI semiconductor QDs usually exhibit a Stokes shift ranging between 50 and 150 meV.

Cadmium

Overview. Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickel-cadmium batteries. First discovered in Germany in 1817, cadmium found early use as a pigment ...
