In non-spherical copper chalcogenide nanoparticles, assignment of the LSPR peaks to the corresponding oscillation modes has been controversial and requires experimental verification. We determined the in-plane LSPR mode of roxbyite Cu\n                    <sub>7<\/sub>\n                    S\n                    <sub>4<\/sub>\n                    nanodisks from the plasmon coupling effect of nanodisks in solution.

This strongly suggests that the singular LSPR peak in the near-infrared region mainly originates from the in-plane oscillation mode. In addition, we demonstrate that the same LSPR peak can be readily tuned by controlling the number of disks in the array.\n                  <\/p>","DOI":"10.1039\/c4fd00239c","type":"journal-article","created":{"date-parts":[[2015,1,6]],"date-time":"2015-01-06T08:03:40Z","timestamp":1420531420000},"page":"355-364","update-policy":"https:\/\/doi.org\/10.1039\/rsc_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Determination of a localized surface plasmon resonance mode of Cu\n                    <sub>7<\/sub>\n                    S\n                    <sub>4<\/sub>\n                    nanodisks by plasmon coupling"],"prefix":"10.1039","volume":"181","author":[{"given":"L.","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Chemistry"},{"name":"Graduate School of Science"},{"name":"Kyoto University"},{"name":"Uji"},{"name":"Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Sakamoto","sequence":"additional","affiliation":[{"name":"Institute for Chemical Science"},{"name":"Kyoto University"},{"name":"Uji"},{"name":"Japan"},{"name":"PRESTO"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Sato","sequence":"additional","affiliation":[{"name":"Institute for Chemical Science"},{"name":"Kyoto University"},{"name":"Uji"},{"name":"Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Teranishi","sequence":"additional","affiliation":[{"name":"Institute for Chemical Science"},{"name":"Kyoto University"},{"name":"Uji"},{"name":"Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"292","published-online":{"date-parts":[[2015]]},"reference":[{"key":"C4FD00239C-(cit1)\/*[position()=1]","doi-asserted-by":"crossref","first-page":"911","DOI":"10.1038\/nmat3151","volume":"10","author":"Linic","year":"2011","journal-title":"Nat.
