This paper reports a convenient method for the synthesis of highly fluorescent Au nanoclusters (NCs) via electrostatically induced phase transfer. Furthermore, on the basis of an aggregation-induced fluorescence quenching mechanism, the potential application for Cu sensing on the fluorescence emission of the Au NCs is discussed. These prepared fluorescent Au NCs offer acceptable sensitivity, high selectivity, and a limit of quantitation of 0.02 μM for the measurement of Cu , which is lower than the maximum level (1 ppm, equals to 15.6 μM) of Cu permitted in drinking water in China. This study contributes to the further development of practical applications with fluorescent NCs.
本文报道了一种通过静电诱导相转移合成高荧光金纳米团簇（NCs）的简便方法。此外，基于聚集诱导荧光猝灭机制，讨论了金纳米团簇荧光发射在铜传感方面的潜在应用。这些制备的荧光金纳米团簇在测量铜时具有可接受的灵敏度、高选择性，定量限为0.02 μM，低于中国饮用水中允许的铜的最大含量（1 ppm，等于15.6 μM）。本研究有助于荧光纳米团簇实际应用的进一步发展。
