The size, height, and spacing of the disks were optimized using finite element simulation to generate a sharp localized surface plasmon resonance peak in the near-infrared wavelength region. The reported results show the possibility of developing an optical gas sensors-based bare Au nanostructures operating at a low temperature.<\/jats:p>","DOI":"10.3390\/s19030647","type":"journal-article","created":{"date-parts":[[2019,2,6]],"date-time":"2019-02-06T03:03:05Z","timestamp":1549422185000},"page":"647","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Gold Nanodisks Plasmonic Array for Hydrogen Sensing at Low Temperature"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4229-7450","authenticated-orcid":false,"given":"Marco","family":"Sturaro","sequence":"first","affiliation":[{"name":"Dipartimento di Ingegneria Industriale, Universit\u00e0 di Padova, 35131 Padova, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1346-1477","authenticated-orcid":false,"given":"Gabriele","family":"Zacco","sequence":"additional","affiliation":[{"name":"Veneto Nanotech, 35100 Padova, Italy"}]},{"given":"Pierfrancesco","family":"Zilio","sequence":"additional","affiliation":[{"name":"Veneto Nanotech, 35100 Padova, Italy"}]},{"given":"Alessandro","family":"Surpi","sequence":"additional","affiliation":[{"name":"Veneto Nanotech, 35100 Padova, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1451-1368","authenticated-orcid":false,"given":"Marco","family":"Bazzan","sequence":"additional","affiliation":[{"name":"Dipartimento di Fisica e Astronomia, Universit\u00e0 di Padova, 35131 Padova, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9601-8640","authenticated-orcid":false,"given":"Alessandro","family":"Martucci","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria Industriale, Universit\u00e0 di Padova, 35131 Padova, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2019,2,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5169","DOI":"10.1063\/1.1647118","article-title":"A study of the reactions of molecular hydrogen with small gold clusters","volume":"120","author":"Varganov","year":"2004","journal-title":"J.
