The QD gel was made from UV glue as the gel matrix and CdSe\/ZnS QDs with a concentration of 1 mg\/mL. The drawing and coating processes were conducted by using a simple and low-cost system developed for this study. Bending, ethanol sensing, temperature response, and time response tests were carried out, respectively. The experimental results showed that the fabricated sensor had a high sensitivity of \u22123.3%\/ppm, a very low temperature cross-sensitivity of 0.17 ppm\/\u00b0C, and a fast response time of 1.1 s. The easily fabricated robust structure and the excellent sensing performance render the sensor a promising platform for real ethanol sensing applications.<\/jats:p>","DOI":"10.3390\/s19020300","type":"journal-article","created":{"date-parts":[[2019,1,14]],"date-time":"2019-01-14T12:20:07Z","timestamp":1547468407000},"page":"300","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["An Ethanol Vapor Sensor Based on a Microfiber with a Quantum-Dot Gel Coating"],"prefix":"10.3390","volume":"19","author":[{"given":"Siqi","family":"Hu","sequence":"first","affiliation":[{"name":"Centre for Optical and Electromagnetic Research, State Key Laboratory of Modern Optical Instrumentation, Zhejiang Provincial Key Laboratory for Sensing Technologies, Zhejiang University, Hangzhou 310058, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9611-726X","authenticated-orcid":false,"given":"Guofeng","family":"Yan","sequence":"additional","affiliation":[{"name":"Zhejiang Lab, Hangzhou 310000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunzhou","family":"Wu","sequence":"additional","affiliation":[{"name":"Centre for Optical and Electromagnetic Research, State Key Laboratory of Modern Optical Instrumentation, Zhejiang Provincial Key Laboratory for Sensing Technologies, Zhejiang University, Hangzhou 310058, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sailing","family":"He","sequence":"additional","affiliation":[{"name":"Centre for Optical and Electromagnetic Research, State Key Laboratory of Modern Optical Instrumentation, Zhejiang Provincial Key Laboratory for Sensing Technologies, Zhejiang University, Hangzhou 310058, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,1,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"196","DOI":"10.1016\/j.snb.2005.11.032","article-title":"Ethanol sensors based on Pt-doped tin oxide nanopowders synthesised by gel-combustion","volume":"117","author":"Neri","year":"2006","journal-title":"Sens.
