title = "Structure-controlled optical thermoresponse in Ruddlesden-Popper layered perovskites",
abstract = "Ruddlesden-Popper perovskites are highly attractive for light-emitting and photonic applications. In these exceptionally deformable frameworks, structural properties strongly impact on the energetic landscape of the material; thus, it is crucial to establish a correlation between the structure and optoelectronic characteristics. Here, we study the structural transformations induced by phase transitions in the butylammonium-based series (BA)(MA)[PbI] (n = 1 and n = 2). We show how thermally driven lattice contraction and changes in crystal packing affect their characteristic absorption and photoluminescence. These findings provide new insights for functional perovskites{\textquoteright} rational design, highlighting the possibility to tune the structural properties through external stimuli to control their functionalities on-demand.",
