The triangular nanoprisms were fabricated by a nanosphere lithography (NSL) method. They have sharp vertices and edges, and are arranged in an ideal hexangular array. These characteristics ensure that they exhibit an excellent LSPR spectrum and a high sensitivity to the exterior environment changes. The LSPR spectra responding to ethanol vapor and four other volatile organic vapors\u2014acetone, benzene, hexane and propanol\u2014were measured with a UV-vis spectrometer in real time. Compared with the other four vapors, ethanol exhibits the highest sensitivity (~0.1 nm\/mg L\u22121) and the lowest detection limit (~10 mg\/L) in the spectral tests. The ethanol vapor test process is also fast (~4 s) and reversible. These insights demonstrate that the triangular nanoprism based nano-sensor can be used in ethanol vapor detection applications.<\/jats:p>","DOI":"10.3390\/s110908643","type":"journal-article","created":{"date-parts":[[2011,9,5]],"date-time":"2011-09-05T11:13:44Z","timestamp":1315221224000},"page":"8643-8653","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["Ethanol Vapor Sensing Properties of Triangular Silver Nanostructures Based on Localized Surface Plasmon Resonance"],"prefix":"10.3390","volume":"11","author":[{"given":"Wenying","family":"Ma","sequence":"first","affiliation":[{"name":"Department of Communication Engineering, Chengdu University of Information Technology, Chengdu 610225, China"},{"name":"State Key Lab of Optical Technologies for Microfabrication, Institute of Optics and Electronics, Chinese Academy of Science, Chengdu 610209, China"}]},{"given":"Huan","family":"Yang","sequence":"additional","affiliation":[{"name":"State Key Lab of Optical Technologies for Microfabrication, Institute of Optics and Electronics, Chinese Academy of Science, Chengdu 610209, China"}]},{"given":"Weimin","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Lab of Optical Technologies for Microfabrication, Institute of Optics and Electronics, Chinese Academy of Science, Chengdu 610209, China"}]},{"given":"Ping","family":"Gao","sequence":"additional","affiliation":[{"name":"State Key Lab of Optical Technologies for Microfabrication, Institute of Optics and Electronics, Chinese Academy of Science, Chengdu 610209, China"}]},{"given":"Jun","family":"Yao","sequence":"additional","affiliation":[{"name":"State Key Lab of Optical Technologies for Microfabrication, Institute of Optics and Electronics, Chinese Academy of Science, Chengdu 610209, China"}]}],"member":"1968","published-online":{"date-parts":[[2011,9,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"18","DOI":"10.1016\/j.snb.2006.09.047","article-title":"Metal oxide-based gas sensor research: How to?","volume":"121","author":"Barsan","year":"2007","journal-title":"Sens.
