WebOct 18, 2024 · As a promising optoelectronic material, all-inorganic perovskite nanocrystals (NCs) have attracted much attention, but there are few studies on zero-dimensional Cs 4 PbBr 6 perovskite NCs. Herein, the in situ growth of the CsPbBr 3 /Cs 4 PbBr 6 NCs inside amorphous glass has been achieved by adjusting the ratios of Cs 2 CO 3 and PbBr … 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.
