Two-dimensional tin halide perovskites are of significant interest for light emitting applications. Here, we investigate the effect organic cation A on stability different Dion–Jacobson tin-based perovskites. The ASnBr4 materials using diammonium with shorter alkyl chains found to exhibit improved stability, exhibiting dramatic difference between most stable HDASnBr4, where HDA denotes 1,6-hexanediammonium, and two 8- 10-carbon chain ammonium cations. HDASnBr4 powders were thermally at 100 °C in an argon environment but exhibited decreasing photoluminescence time ambient air °C. sample degradation is accelerated compared room temperature, it proceeds along similar pathways, namely phase transformation followed by perovskite decomposition. Light emission from thin films could be further enhanced methanol vapor treatment, warm white Commission Internationale de l’Eclairage (CIE) coordinates (0.37, 0.34) obtained combining a blue-emitting polymer film, while direct mixing blue phosphor powder yields CIE (0.34, 0.32).
