Water-soluble ZnSe/ZnS quantum dots (QDs) are semiconductor quantum dot materials with core-shell structure, in which the core is composed of zinc selenide (ZnSe) and the shell is composed of zinc sulfide (ZnS). Epitaxial growth of a protective ZnS shell on a ZnSe core is a key strategy to achieve high fluorescence quantum efficiency and essential stability. Water-soluble ZnSe/ZnS QDs produced by Alfa Chemistry can achieve very narrow emission peaks and good photoluminescence quantum yield, which makes them an attractive choice for the quantum dot light-emitting diode (QD-LED) application.
