“…金属纳米簇是一种尺寸约为2 nm，介于金属原子和金属纳米颗粒之间的纳米材料 [3] ，近几十年人们对金、银等贵金属纳米簇进行了广泛的研究 [4] ，而与金、银同一族的铜，一直到近些年才引起人们的重视。与金、银相比，铜的相对含量丰富，价格低廉且易于获取，铜纳米簇不仅与金、银等纳米簇具有相似的光化学性质，其生物相容性更高，环境友好，具有广泛的应用前景。因小尺寸的金属纳米簇在溶液中易发生聚集，因此在制备金属纳米簇时通常向其中加入稳定剂，即通过模板法制备金属纳米簇，目前用于稳定金属纳米簇的模板有树枝状分子、DNA、蛋白质、巯基小分子等 [5][6][7][8] 。模板法也是目前制备铜纳米簇的主要方法 [9]…”

This paper proposed a comprehensive analysis chemical experiment. The experiment contents including preparation of fluorescent copper nanoclusters, fluorescent spectroscopic characterization, and hydrogen peroxide detection based on fluorometry. This experiment can not only make students understand the fluorescent metal nanoclusters and monitoring methods of hydrogen peroxide, but also allow students to learn operation methods and fundamental principles of magnetic stirring, darkbox type ultraviolet analyzer, lab-dancer and fluorescence spectrophotometer. Moreover, this experiment will make students establish an academic idea of optimizing experimental conditions and comprehensively analyzing problems, which is helpful for cultivating students' comprehensive innovation capability.

In the past several decades, noble metal nanoclusters (NMNCs) have been developed as an emerging class of luminescent materials due to their superior photo-stability and biocompatibility, but their luminous quantum yield is relatively low and the physical origin of the bright photoluminescence (PL) of NMNCs remain elusive, which limited their practical application. As the well-defined structure and composition of NMNCs have been determined, in this mini-review, the effect of each component (metal core, ligand shell and interfacial water) on their PL properties and corresponded working mechanism were comprehensively introduced, and a model that structural water molecules dominated p band intermediate state was proposed to give a unified understanding on the PL mechanism of NMNCs and a further perspective to the future developments of NMNCs by revisiting the development of our studies on the PL mechanism of NMNCs in the past decade.
