摘要

One-pot synthesis of water-soluble Cu NCs using DHLA protection ligands by different reducing reagents including NaBH _(4) , N _(2) H _(4) and THPC was developed. Furthermore, it was found that the as prepared Cu NCs using THPC as a reducing reagent describe fluorescence enhancement in the presence of Zn ~(2+) and Al ~(3+) . It is proposed that the binding of Zn ~(2+) and Al ~(3+) to OH on the copper core of Cu NCs promotes the formation of CuNC–OH–Zn–OH–Cu NCs and CuNC–OH–Al–OH–Cu NCs aggregates respectively, which enables aggregation induced fluorescence enhancement. Additionally, it was found that the fluorescence enhancement were partly reversible by the introduction of an alkaline buffer solution and Zn ~(2+) .
