Moreover, the controlled synthesis of Sb<sup>3+<\/sup>-doped 0D In-based halide NCs and the size effect on the optical properties and excited-state dynamics remain unexplored.  <\/p>\n<p>In a study published in <i>Nano Today<\/i>, the research group led by Prof. CHEN Xueyuan from Fujian Institute of Research on the Structure of Matter (FJIRSM) of the Chinese Academy of <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">Science<\/a>s (CAS) reported the controlled synthesis of Sb<sup>3+<\/sup>-doped 0D Cs<sub>3<\/sub>InCl<sub>6<\/sub> NCs with tunable sizes and investigated the effect of NC size on the optical properties and excited-state dynamics of Sb<sup>3+<\/sup>. <\/p>\n<p>The researchers obtained 0D Cs<sub>3<\/sub>InCl<sub>6<\/sub>: Sb<sup>3+<\/sup> NCs with tunable sizes by the controlled synthesis based on a HCl hot-injection method. The as-synthesized NCs exhibit bright green PL with a broad emission band.  <\/p>\n<p>They comprehensively surveyed the effects of NC size and Sb<sup>3+<\/sup> concentration on the electronic structures and PL properties of the NCs and the excited-state dynamics of Sb<sup>3+<\/sup> by means of temperature-dependent steady-state and transient PL and ultrafast femtosecond transient absorption (fs-TA) spectroscopies.  <\/p>\n<p>Owing to the strong electron-phonon coupling of Sb<sup>3+<\/sup> in the spatially confined 0D structure of Cs<sub>3<\/sub>InCl<sub>6<\/sub>, Sb<sup>3+<\/sup> ions experienced a dynamic Jahn-Teller distortion in the <sup>3<\/sup>P<sub>1<\/sub> excited state and an off-center position in the <sup>1<\/sup>S<sub>0<\/sub> ground state, which resulted in intense broadband emission of Sb<sup>3+<\/sup> from the inter-configurational <sup>3<\/sup>P<sub>1<\/sub> \u2192 <sup>1<\/sup>S<sub>0<\/sub> transition with a large Stokes shift and a high PL quantum yield (QY) of 52.3%. <\/p>\n<p>Furthermore, taking advantage of the hydroscopicity of the NCs, the researchers demonstrated the water-triggered chemical transformation of the NCs from green-emitting Cs<sub>3<\/sub>InCl<sub>6<\/sub>: Sb<sup>3+<\/sup> to orange-emitting Cs<sub>2<\/sub>InCl<sub>5<\/sub>\u00b7H<sub>2<\/sub>O: Sb<sup>3+<\/sup> with a PLQY up to 75.3%, thus revealing the superiority of the Sb<sup>3+<\/sup> luminescence in metal halide NCs. <\/p>\n<p>These findings provide fundamental insights into the excited-state dynamics of Sb<sup>3+<\/sup> in 0D In-based halide NCs, thereby laying a foundation for future design of novel lead-free metal halide NCs with tunable structure and switchable PL through ns<sup>2<\/sup>-metal ion doping or alloying towards versatile applications such as luminescent chemosensors.<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            Cu+ doping enhances self-trapped exciton emission in alloyed Cs2(Ag\/Na)InCl6 double perovskite\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Zhongliang Gong et al, Highly efficient Sb3+ emitters in 0D cesium indium chloride nanocrystals with switchable photoluminescence through water-triggered structural transformation, <i>Nano Today<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1016\/j.nantod.2022.101460\">DOI: 10.1016\/j.nantod.2022.101460<\/a><\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    Chinese Academy of Sciences<br \/>\n                                                                                                        <a rel=\"nofollow noopener\" target=\"_blank\" class=\"icon_open\" href=\"https:\/\/english.cas.cn\/\"><br \/>\n                                                        <svg>\n                                                            <use href=\"https:\/\/phys.b-cdn.net\/tmpl\/v6\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n                                                        <\/svg><br \/>\n                                                    <\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 Highly emissive Sb3+-doped 0D cesium indium chloride nanocrystals with switchable photoluminescence (2022, May 19)<br \/>\n                                                 retrieved 19 May 2022<br \/>\n                                                 from https:\/\/phys.org\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-05-highly-emissive-sb3-doped-0d-cesium.html<\/p>\n<p>                                            This document is subject to copyright.
