All the samples had a rodlike morphology, with a diameter of ∼14 nm and a length of ∼30-100 nm. Alloying did not alter the crystal structure of the host Cs₃ZnCl₅ NCs, and Cu ions were mainly introduced in the oxidation state +1 according to X-ray photoelectron and electron paramagnetic resonance spectroscopies. The spectroscopic analysis of unalloyed, Cu-alloyed, Mn-alloyed, and Cu, Mn coalloyed NCs indicated that (i) the Cs₃ZnCl₅ NCs have a large band gap of ∼5.35 eV; (ii) Cu(I) aliovalent alloying leads to an absorption shoulder/peak at ∼4.8 eV and cyanChemistry of materials : a publication of the American Chemical Society8603-8612https://www.ebi.ac.uk/biostudies/studies/S-EPMC9558458biostudies-literatureCu⁺ → Mn²⁺ Energy Transfer in Cu, Mn Coalloyed Cs₃ZnCl₅ Colloidal Nanocrystals.PMC9558458Infante IZaffalon MLToso SXia ZDe Trizio LZito JBrovelli SFanciulli MZhu DLiu YMoro FCova FManna LfalseCu⁺ → Mn²⁺ Energy Transfer in Cu, Mn Coalloyed Cs₃ZnCl₅ Colloidal Nanocrystals.In this work, we report the hot-injection synthesis of Cs₃ZnCl₅ colloidal nanocrystals (NCs) with tunable amounts of Cu⁺ and Mn²⁺ substituent cations.
