The intrinsic quantum confinement effects originating from low\u2010dimensional electronic structure lead to high photoluminescence quantum yields (PLQYs). Among them, Cs<jats:sub>3<\/jats:sub>Cu<jats:sub>2<\/jats:sub>I<jats:sub>5<\/jats:sub> is the most promising candidate, satisfying both high PLQY and air stability. In this study, a strategy to explore a new material meeting these requirements through the use of the mixed\u2010anions of I<jats:sup>\u2212<\/jats:sup> and Cl<jats:sup>\u2212<\/jats:sup> is proposed. The expectation is maintained that the large difference in ionic radii between them likely results in the formation of a novel compound. Consequently, Cs<jats:sub>5<\/jats:sub>Cu<jats:sub>3<\/jats:sub>Cl<jats:sub>6<\/jats:sub>I<jats:sub>2<\/jats:sub> with a 1D zigzag chain structure is discovered. This material exhibits blue emission (\u2248462\u00a0nm) with a near\u2010unity quantum yield of 95%. An electronic structure calculation reveals that the localized nature of the valence band maximum is crucial in obtaining efficient self\u2010trapped exciton emission. Moreover, the iodine\u2010bridged 1D connectivity significantly enhances the chemical stability of Cs<jats:sub>5<\/jats:sub>Cu<jats:sub>3<\/jats:sub>Cl<jats:sub>6<\/jats:sub>I<jats:sub>2<\/jats:sub>, compared with the pure chloride phase. The present findings provide a new perspective for developing air\u2010stable alkali copper(I) halides with highly efficient luminescence.<\/jats:p>","DOI":"10.1002\/adma.202002945","type":"journal-article","created":{"date-parts":[[2020,8,6]],"date-time":"2020-08-06T05:32:55Z","timestamp":1596691975000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":119,"title":["A Highly Efficient and Stable Blue\u2010Emitting Cs<sub>5<\/sub>Cu<sub>3<\/sub>Cl<sub>6<\/sub>I<sub>2<\/sub> with a 1D Chain Structure"],"prefix":"10.1002","volume":"32","author":[{"given":"Jiangwei","family":"Li","sequence":"first","affiliation":[{"name":"Materials Research Center for Element Strategy Tokyo Institute of Technology  Mailbox SE\u20101, 4259 Nagatsuta, Midori\u2010ku Yokohama 226\u20108503 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Inoshita","sequence":"additional","affiliation":[{"name":"Materials Research Center for Element Strategy Tokyo Institute of Technology  Mailbox SE\u20101, 4259 Nagatsuta, Midori\u2010ku Yokohama 226\u20108503 Japan"},{"name":"National Institute for Materials Science  Tsukuba Ibaraki 305\u20100044 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianping","family":"Ying","sequence":"additional","affiliation":[{"name":"Materials Research Center for Element Strategy Tokyo Institute of Technology  Mailbox SE\u20101, 4259 Nagatsuta, Midori\u2010ku Yokohama 226\u20108503 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsushi","family":"Ooishi","sequence":"additional","affiliation":[{"name":"Science and Innovation Center Mitsubishi Chemical Corporation  1000 Kamoshida\u2010cho, Aoba\u2010ku Yokohama Kanagawa 227\u20108502 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9168-6260","authenticated-orcid":false,"given":"Junghwan","family":"Kim","sequence":"additional","affiliation":[{"name":"Materials Research Center for Element Strategy Tokyo Institute of Technology  Mailbox SE\u20101, 4259 Nagatsuta, Midori\u2010ku Yokohama 226\u20108503 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideo","family":"Hosono","sequence":"additional","affiliation":[{"name":"Materials Research Center for Element Strategy Tokyo Institute of Technology  Mailbox SE\u20101, 4259 Nagatsuta, Midori\u2010ku Yokohama 226\u20108503 Japan"},{"name":"National Institute for Materials Science  Tsukuba Ibaraki 305\u20100044 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,8,6]]},"reference":[{"key":"e_1_2_5_1_1","doi-asserted-by":"publisher","DOI":"10.1038\/nphoton.2009.32"},{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature04645"},{"key":"e_1_2_5_3_1","first-page":"128","volume":"92","author":"Allen S.
