The 3D CsPbX3 structure has set the standard with many studies currently attempting to substitute lead with other metals while retaining the properties of this material. This effort has led to the fabrication of metal halides with lower dimensionality, wherein particular 2D layered perovskite structures have captured attention as inspiration for the next generation of colloidal semiconductors. Here we report the synthesis of the Ruddlesden\u2013Popper Cs2CdCl4:Sb3+ phase as colloidal nanoplatelets (NPs) using a facile hot injection approach under atmospheric conditions. Through strict adjustment of the synthesis parameters with emphasis on the ligand ratio, we obtained NPs with a relatively uniform size and good morphological control. The particles were characterized through transmission electron microscopy, synchrotron X-ray diffraction, and pair distribution function analysis. The spectroscopic characterization revealed most strikingly an intense cyan emission under UV excitation with a measured PLQY of \u223c20%. The emission was attributed to the Sb3+-doping within the structure.<\/jats:p>","DOI":"10.1021\/acsnano.1c05684","type":"journal-article","created":{"date-parts":[[2021,10,20]],"date-time":"2021-10-20T20:30:55Z","timestamp":1634761855000},"page":"17729-17737","source":"Crossref","is-referenced-by-count":69,"title":["Cyan\nEmission in Two-Dimensional Colloidal Cs2CdCl4:Sb3+ Ruddlesden\u2013Popper\nPhase Nanoplatelets"],"prefix":"10.1021","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1794-8282","authenticated-orcid":true,"given":"Federico","family":"Locardi","sequence":"first","affiliation":[{"name":"Universita\u0300 degli Studi di Genova , , Via Dodecaneso 31 , ,","place":["Genova, Italy, 16146"]},{"name":"Ghent University , , Krijgslaan 281 , ,","place":["Gent, Belgium, 9000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0442-5420","authenticated-orcid":true,"given":"Margarita","family":"Samoli","sequence":"additional","affiliation":[{"name":"Ghent University , , Krijgslaan 281 , ,","place":["Gent, Belgium, 9000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8391-3486","authenticated-orcid":true,"given":"Alberto","family":"Martinelli","sequence":"additional","affiliation":[{"name":"CNR-SPIN , Corso Perrone 24 , ,","place":["Genova, Italy, I-16152"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2212-965X","authenticated-orcid":true,"given":"Onur","family":"Erdem","sequence":"additional","affiliation":[{"name":"Ghent University , , Krijgslaan 281 , ,","place":["Gent, Belgium, 9000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Debora Vale","family":"Magalhaes","sequence":"additional","affiliation":[{"name":"University of Antwerp , , Groenenborgerlaan 171 , ,","place":["Antwerp, Belgium, 2020"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4249-8017","authenticated-orcid":true,"given":"Sara","family":"Bals","sequence":"additional","affiliation":[{"name":"University of Antwerp , , Groenenborgerlaan 171 , ,","place":["Antwerp, Belgium, 2020"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7041-3375","authenticated-orcid":true,"given":"Zeger","family":"Hens","sequence":"additional","affiliation":[{"name":"Ghent University , , Krijgslaan 281 , ,","place":["Gent, Belgium, 9000"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2021,10,20]]},"reference":[{"key":"2026081810155617100_cit1","doi-asserted-by":"publisher","first-page":"3692","DOI":"10.1021\/nl5048779","article-title":"Nanocrystals\nof Cesium Lead Halide Perovskites (CsPbX3, X = Cl, Br,\nand I): Novel Optoelectronic Materials Showing Bright Emission with\nWide Color Gamut","volume":"15","author":"Protesescu","year":"2015","journal-title":"Nano Lett."},{"key":"2026081810155617100_cit2","doi-asserted-by":"publisher","first-page":"10775","DOI":"10.1021\/acsnano.0c08903","article-title":"State\nof the Art and\nProspects for Halide Perovskite Nanocrystals","volume":"15","author":"Dey","year":"2021","journal-title":"ACS Nano"},{"key":"2026081810155617100_cit3","doi-asserted-by":"publisher","first-page":"6050","DOI":"10.1021\/ja809598r","article-title":"Organometal Halide\nPerovskites as Visible-Light Sensitizers for Photovoltaic Cells","volume":"131","author":"Kojima","year":"2009","journal-title":"J.
