Among them, 0D perovskites, characterized by unique crystallographic\/electronic structures with isolated metal halide octahedra, exhibit tremendous potential as light emitters with self\u2010trapped exciton (STE). However, the modulation of STE emission characteristics in 0D perovskites primarily focuses on regulating B\u2010 or X\u2010site elements. In this work, a lead\u2010free compound, Sb<jats:sup>3+<\/jats:sup>\u2010doped ((C<jats:sub>2<\/jats:sub>H<jats:sub>5<\/jats:sub>)<jats:sub>2<\/jats:sub>NH<jats:sub>2<\/jats:sub>)<jats:sub>3<\/jats:sub>InCl<jats:sub>6<\/jats:sub> single crystal, which exhibits a high photoluminescence quantum yield, is synthesized, and with increasing temperature, the A\u2010site organic cations undergo a transition from an ordered configuration to a disordered one, accompanied by a redshift in the STE emission. Furthermore, Hirshfeld surface calculations reveal that high temperatures enhance the thermal vibrations of SbCl<jats:sub>6<\/jats:sub><jats:sup>3\u2212<\/jats:sup> clusters and the octahedra distortion, which are responsible for the redshift. Since this thermally triggered transition of A\u2010site order is reversible, it can be exploited for temperature\u2010sensing applications. Overall, in this work, valuable insights are provided into the role of A\u2010site cations in modulating STE emission and the design of efficient light emitters.<\/jats:p>","DOI":"10.1002\/smsc.202400443","type":"journal-article","created":{"date-parts":[[2024,11,22]],"date-time":"2024-11-22T11:59:19Z","timestamp":1732276759000},"source":"Crossref","is-referenced-by-count":11,"title":["Strong Correlation Between A\u2010Site Cation Order and Self\u2010Trapped Exciton Emission in 0D Hybrid Perovskites"],"prefix":"10.1002","volume":"5","author":[{"given":"Feier","family":"Fang","sequence":"first","affiliation":[{"name":"International Collaborative Laboratory of 2D Materials for Optoelectronics Science and Technology of Ministry of Education Institute of Microscale Optoelectronics Shenzhen University  Shenzhen 518060 P.
