In this paper, a simple, green, clean, and time-saving chemical etching method was used to synthesize water-soluble Cu NCs using ascorbic acid (AA) as the reducing agent. The as-prepared Cu NCs showed strong green fluorescence (with a quantum yield as high as 33.6%) and high ion stability, and good antioxidant activity as well. The resultant Cu NCs were used for the detection of 4-aminoazobenzene (one of 24 kinds of prohibited textile compounds) in water with a minimum detection limit of 1.44 \u03bcM, which has good potential for fabric safety monitoring.<\/jats:p>","DOI":"10.3390\/nano10081531","type":"journal-article","created":{"date-parts":[[2020,8,5]],"date-time":"2020-08-05T06:02:21Z","timestamp":1596607341000},"page":"1531","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Highly Luminescent Copper Nanoclusters Stabilized by Ascorbic Acid for the Quantitative Detection of 4-Aminoazobenzene"],"prefix":"10.3390","volume":"10","author":[{"given":"Qiang","family":"Li","sequence":"first","affiliation":[{"name":"Hubei Collaborative Innovation Center for Advanced Organic Chemical Materials, Ministry of Education, Key Laboratory of Green Preparation and Application for Functional Materials, Hubei Key Laboratory of Polymer Materials, School of Materials Science &amp;
