Effects on the emission discrepancy between two-dimensional Sn-based and Pb-based perovskites
文献摘要：
Two-dimensional[2D]Sn-based perovskites are a kind of non-toxic environment-friendly emission material with low photo-luminescence quantum yields[PLQYs]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 fab-ricate (BA)2Snl4 and (BA)2Pbl4 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,significantly broadening the emission linewidth and accelerating the exciton relaxation process,which significantly reduces the PLQY of 2D Sn-based perovskites.
