The aqueous dispersion of ZnO quantum dots (QDs) with strong blue emission (quantum yield of 76%) was synthesized through a simple solution route. The water stability of such QDs is provided by the hydroxyl groups on their surface, and the strong blue emission is suggested to arise from the formation of surface ZnO/oleic acid complexes. Under irradiation, these complexes are thought to absorb the excitation light with 3.54 eV and then generate the blue emission with 2.82 eV.
通过简单的溶液法合成了具有强蓝光发射（量子产率为76%）的ZnO量子点水分散体。此类量子点的水稳定性由其表面的羟基提供，而强蓝光发射被认为源于表面ZnO/油酸络合物的形成。在光照下，这些络合物被认为吸收3.54 eV的激发光，然后产生2.82 eV的蓝光发射。
