Abstract

Mn²⁺ doping imposes intriguing optoelectronic properties on lead-halide perovskites; however, its impact on their crystal structure remains unclear. This study investigates the consequences of interstitial and substitutional Mn²⁺ doping on the lattice-strain and interplanar spacings of 2D perovskites and correlates the structural changes to their optical properties.
