描述

一般說明

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 (S^2–). 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.
