Here, a tapered fiber sensor made from Ge10As30Se40Te20 glass fiber was reported. The fundamental modes and intensity of evanescent waves in fibers with different diameters were simulated with COMSOL. The 30 mm length tapered fiber sensors with different waist diameters, 110, 63, and 31 \u03bcm, were fabricated for ethanol detection. The sensor with a waist diameter of 31 \u03bcm has the highest sensitivity of 0.73 a.u.\/% and a limit of detection (LoD) of 0.195 vol.% for ethanol. Finally, this sensor has been used to analyze alcohols, including Chinese baijiu (Chinese distilled spirits), red wine, Shaoxing wine (Chinese rice wine), Rio cocktail, and Tsingtao beer. It is shown that the ethanol concentration is consistent with the nominal alcoholicity. Moreover, other components such as CO2 and maltose can be detected in Tsingtao beer, demonstrating the feasibility of its application in detecting food additives.<\/jats:p>","DOI":"10.3390\/s23104841","type":"journal-article","created":{"date-parts":[[2023,5,18]],"date-time":"2023-05-18T07:35:50Z","timestamp":1684395350000},"page":"4841","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Infrared Evanescent Wave Sensing Based on a Ge10As30Se40Te20 Fiber for Alcohol Detection"],"prefix":"10.3390","volume":"23","author":[{"given":"Zijian","family":"Li","sequence":"first","affiliation":[{"name":"State Key Laboratory of Silicate Materials for Architectures, Wuhan University of Technology, Wuhan 430070, China"},{"name":"School of Materials Science and Engineering, Wuhan University of Technology, Wuhan 430070, China"}]},{"given":"Yongkun","family":"Zhao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Silicate Materials for Architectures, Wuhan University of Technology, Wuhan 430070, China"},{"name":"School of Materials Science and Engineering, Wuhan University of Technology, Wuhan 430070, China"}]},{"given":"Tianxiang","family":"You","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Silicate Materials for Architectures, Wuhan University of Technology, Wuhan 430070, China"},{"name":"School of Materials Science and Engineering, Wuhan University of Technology, Wuhan 430070, China"}]},{"given":"Jihong","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Wuhan University of Technology, Wuhan 430070, China"},{"name":"State Key Laboratory of Optical Fiber and Cable Manufacture Technology, Yangtze Optical Fibre and Cable Joint Stock Limited Company (YOFC), Wuhan 430073, China"}]},{"given":"Mengling","family":"Xia","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Wuhan University of Technology, Wuhan 430070, China"}]},{"given":"Ping","family":"Lu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Silicate Materials for Architectures, Wuhan University of Technology, Wuhan 430070, China"},{"name":"School of Materials Science and Engineering, Wuhan University of Technology, Wuhan 430070, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2180-6543","authenticated-orcid":false,"given":"Xianghua","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Silicate Materials for Architectures, Wuhan University of Technology, Wuhan 430070, China"},{"name":"Institut Des Sciences Chimiques de Rennes UMR 6226, Centre National de la Recherche Scientifique (CNRS), Universit\u00e9 de Rennes 1, 35042 Rennes, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1887-0632","authenticated-orcid":false,"given":"Yinsheng","family":"Xu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Silicate Materials for Architectures, Wuhan University of Technology, Wuhan 430070, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Memon, S.F., Wang, R., Strunz, B., Chowdhry, B.S., Pembroke, J.T., and Lewis, E.
