Two emissions peaks of CdTe QDs at 572\u00a0nm and GCNNs at 436\u00a0nm are both excitated at 340\u00a0nm. Under a UV lamp, fluorescent of traffic yellow CdTe QDs is linearly quenched by Cu<jats:sup>2+<\/jats:sup> (as the detection signal), while blue GCNNs remains unchanged (as the reference), resulting in a distinguishable color change gradually from pink yellow to blue. The limit of detection (LOD) of this new sensor for Cu<jats:sup>2+<\/jats:sup> is as low as 0.47\u00a0ng\u00a0mL<jats:sup>\u22121<\/jats:sup> with 1.4 % RSD. The established method has been successfully applied to detection of Cu<jats:sup>2+<\/jats:sup> in various drinks with satisfactory results. Moreover, a paper\u2010based sensor, which has been prepared by soaking cellulose acetate membrane in CdTe QDs\/GCNNs sensor solution, has a wide semiquantitative detection range for Cu<jats:sup>2+<\/jats:sup> (0.01\u00a0~\u00a05.0\u00a0\u03bcg\u00a0mL<jats:sup>\u22121<\/jats:sup>). It has realized successfully on\u2010site and rapid determination of Cu<jats:sup>2+<\/jats:sup> in red wine without any pretreatment procedure and is of great promotion and application value in determination of Cu<jats:sup>2+<\/jats:sup> in liquid samples.<\/jats:p>","DOI":"10.1111\/php.13271","type":"journal-article","created":{"date-parts":[[2020,4,3]],"date-time":"2020-04-03T15:31:12Z","timestamp":1585927872000},"page":"1154-1160","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Ratiometric Fluorescent Paper\u2010Based Sensor Based on CdTe Quantum Dots and Graphite Carbon Nitride Hybrid for Visual and Rapid Determination of Cu<sup>2+<\/sup> in Drinks"],"prefix":"10.1111","volume":"96","author":[{"given":"Kaili","family":"He","sequence":"first","affiliation":[{"name":"Hubei Collaborative Innovation Center for Rare Metal Chemistry Hubei Key Laboratory of Pollutant Analysis &amp; Reuse Technology Institute for Advanced Materials College of Chemistry and Chemical Engineering Hubei Normal University Huangshi 435002 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Zhan","sequence":"additional","affiliation":[{"name":"Hubei Collaborative Innovation Center for Rare Metal Chemistry Hubei Key Laboratory of Pollutant Analysis &amp; Reuse Technology Institute for Advanced Materials College of Chemistry and Chemical Engineering Hubei Normal University Huangshi 435002 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lian","family":"Liu","sequence":"additional","affiliation":[{"name":"Hubei Collaborative Innovation Center for Rare Metal Chemistry Hubei Key Laboratory of Pollutant Analysis &amp; Reuse Technology Institute for Advanced Materials College of Chemistry and Chemical Engineering Hubei Normal University Huangshi 435002 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaohong","family":"Ruan","sequence":"additional","affiliation":[{"name":"Hubei Collaborative Innovation Center for Rare Metal Chemistry Hubei Key Laboratory of Pollutant Analysis &amp; Reuse Technology Institute for Advanced Materials College of Chemistry and Chemical Engineering Hubei Normal University Huangshi 435002 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5735-3622","authenticated-orcid":false,"given":"Yiwei","family":"Wu","sequence":"additional","affiliation":[{"name":"Hubei Collaborative Innovation Center for Rare Metal Chemistry Hubei Key Laboratory of Pollutant Analysis &amp; Reuse Technology Institute for Advanced Materials College of Chemistry and Chemical Engineering Hubei Normal University Huangshi 435002 China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,5,19]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.snb.2014.06.054"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.microc.2008.01.008"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1039\/C5AN01297J"},{"key":"e_1_2_7_5_1","volume-title":"Prescription for Nutritional Healing","author":"Balch P.
