Narrowband Emitting Tin Dion–Jacobson Perovskites through Systematic Spacer Cation Design to Suppress Metal Lone-Pair Anisotropy
Two-dimensional (2D) Dion-Jacobson (DJ) tin perovskites are promising lead-free semiconductors, yet the limited number of phases reported and their frequently broad and asymmetric photoluminescence (PL) have hindered mechanistic understanding and rational design of their optoelectronic properties. Here, we systematical...
