Abstract

The spacer cation in two-dimensional (2D) Ruddlesden–Popper lead halide perovskites dictates photoinduced phase segregation. Halide ion segregation under steady-state irradiation of single-layer (n = 1) 2D perovskites is seen when butylammonium (BA) is used as the spacer cation, whereas it is essentially absent when BA is replaced with phenethylammonium (PEA).
