Abstract

Two-dimensional (2D) Sn-based perovskites are a kind of non-toxic environment-friendly emission material with low photoluminescence quantum yields (PLQY) and enhanced emission linewidths compared to that of 2D Pb-based perovskites. However, there is no work systematically elucidating the reasons for the differences in the emission properties.

We fabricate (BA)₂SnI₄ and (BA)₂PbI₄ having different defect densities and different exciton-phonon scattering intensities. We also reveal that 2D Sn-based perovskites have stronger exciton-phonon scattering intensity and higher defects density, making significantly broadening the emission linewidth and accelerating the exciton relaxation process, which significantly reduces the PLQY of 2D Sn-based perovskites.
