Abstract:In this article, the water-soluble blue-light-emitting copper nanoclusters (CuNCs) were prepared by polyvinylpyrrolidone (PVP) and ascorbic acid as templating and reducing agents severally. Optimization of synthesis conditions of PVP-CuNCs were studied and analyzed. It had good specificity and exceptional sensitivity detection for sodium dichloroisocyanurate (DCCNa)/rosmarinic acid (RA), with a linear response range of 0.03–2.4/0.03–0.9 µM and corresponding LOD value of 10.77/8.98 nM. Moreover, the fluorescent… Show more
