This paper focuses on a specific layered organic-inorganic Ruddlesden-Popper hybrid perovskite, within the family of 2D alkylammonium lead halide perovskites (2D ALHPs), described by the chemical composition of (BA) 2 (MA)Pb 2 I 7 . In this composition, the halide element is iodide (I), and the divalent transition metal is lead (Pb). MA represents the methylammonium cation with the formula (CH) 3 (NH) 3 , which occupies the interstitial sites within the PbI 6 octahedra. BA, the butylammonium cation with the chemical formula C 4 H 12 N + , acts as the spacer cation, separating the double-layered PbI 6 octahedra.
