Structural Rigidity Enables Amplified Spontaneous Emission in 2D Alkylammonium Tin Perovskites
Two-dimensional tin perovskites are attracting increasing attention for coherent light emission, yet the impact of organic cations on their properties remains poorly understood. Here, we compare the Ruddlesden–Popper (RP) butylammonium tin iodide (BA2SnI4) and Dion–Jacobson (DJ) 1,4-diammoniobutane tin iodide (DABSnI4)...
