Significant attentions directed toward tin-based perovskites as potential replacements for lead halide perovskites in the production of optoelectronic devices. The primary issue associated with tin-based perovskites pertains to their stability. Additionally, other factors such as the cost of precursor materials for synthesis and the operational stability of LED devices are also important considerations. In this context, this study introduces an efficient and straightforward method for synthesizing 2D perovskite microcrystal powder, specifically (4-fluorophenethylammonium)2SnX4 (X=I/Br). This method employs affordable starting materials and addresses both adequate ambient stability and the extended inert atmosphere storage of the microcrystal powder. Furthermore, these perovskite powders are further processed into thin films, which are then utilized in the fabrication of LED devices. The two-step recrystallized devices exhibit superior performance and operational stability when compared to reference devices produced using conventional methods and commercial precursors. The established synthesis approach is considered a versatile method for producing various hybrid tin-based perovskite microcrystal powders, which can be used in the manufacturing of LED devices.
