WebMay 6, 2024 · Benefitting from the unique Pb 2+-poor and Br −-rich reaction environment, the Sn cation is successfully introduced into the Cs 4 PbBr 6 NCs, forming coexisting point defects comprising substitutional Sn Pb and interstitial Br i, thereby endowing these theoretically nonluminescent Cs 4 PbBr 6 NCs with an ultranarrow blue emission at … WebJul 22, 2024 · Abstract. Cs4PbBr6 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 6-coordinate geometry to six equivalent Br1- atoms. All Cs–Br bond lengths are 3.62 Å.
