However, the lack of low-energy light-emitting compounds prohibits their further applications. Herein, we report an orange\u2013red emissive (C\n                    <jats:sub>19<\/jats:sub>\n                    H\n                    <jats:sub>18<\/jats:sub>\n                    P)\n                    <jats:sub>2<\/jats:sub>\n                    Cu\n                    <jats:sub>4<\/jats:sub>\n                    Br\n                    <jats:sub>6<\/jats:sub>\n                    with a zero-dimensional structure. The photoluminescence (PL) peak of (C\n                    <jats:sub>19<\/jats:sub>\n                    H\n                    <jats:sub>18<\/jats:sub>\n                    P)\n                    <jats:sub>2<\/jats:sub>\n                    Cu\n                    <jats:sub>4<\/jats:sub>\n                    Br\n                    <jats:sub>6<\/jats:sub>\n                    locates at 640\u2005nm with a PL quantum yield of 69.3%, and the large Stokes shift is 245\u2005nm. Experimental analyses demonstrate the bright broadband orange\u2013red light emission derived from the synergistic effect of metal-to-ligand charge transfer or halide-to-ligand charge transfer (MLCT\/HLCT) excited state and cluster-centered (CC) excited state.

This work not only demonstrates material design strategies for preparing low-energy emissive OIHCMHs but also inspires the potential of low-dimensional metal halides in high quality white LED applications.\n                  <\/jats:p>","DOI":"10.1364\/ol.555288","type":"journal-article","created":{"date-parts":[[2025,3,24]],"date-time":"2025-03-24T07:15:31Z","timestamp":1742800531000},"page":"2731","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Orange\u2013red emissive organic\u2013inorganic hybrid copper halide for white light-emitting diode application"],"prefix":"10.1364","volume":"50","author":[{"given":"Lingling","family":"Xie","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ning","family":"Lv","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuelu","family":"Wang","sequence":"additional","affiliation":[{"name":"BOE Technology Group Co., Ltd."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhe","family":"Liu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huihui","family":"Pi","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xitao","family":"Li","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henan","family":"Yang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siyi","family":"Li","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheng","family":"Ding","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dengming","family":"Huang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pengcheng","family":"Mao","sequence":"additional","affiliation":[{"name":"Beijing Institute of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhengguo","family":"Lin","sequence":"additional","affiliation":[{"name":"Hebei Normal University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3714-166X","authenticated-orcid":true,"given":"Bingkun","family":"Chen","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01skt4w74","id-type":"ROR","asserted-by":"publisher"}]},{"name":"The State Key Laboratory of Luminescent Materials and Devices"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2025,4,14]]},"reference":[{"key":"ol-50-8-2731-R1","doi-asserted-by":"publisher","first-page":"2313247","DOI":"10.1002\/adma.202313247","volume":"36","author":"Han","year":"2024","journal-title":"Adv.
