Descrição geral

Copper indium sulfide zinc sulfide (CuInS2/ZnS) core/shell quantum dots are a heavy metal-free, high-performance alternative to cadmium-based quantum dots. CuInS2 QDs, as the I–III–VI ternary semiconductor nanocrystals contain two cations (Cu+ and In3+) and one anion (S2–). These QDs have unique photophysical properties; that make them superior to molecular dyes. Advantages of QDs include higher photostability, broad absorption spectrum, high extinction coefficients, and tunable optical and electronic properties.

CuInS2/ZnS quantum dots possess brilliant quantum yield and excellent long-term stability, and these non-toxic quantum dots lack the environmental hazards of cadmium-based quantum dots.
