This research explores the use of natural antioxidants as additives to improve the fabrication of environmentally friendly Sn-based perovskite films, tackling oxidation and crystallization challenges. Ascorbic acid is highlighted for its effectiveness against oxidation, and when combined with 18-Crown-6, it enhances 2D red Sn-based PeLED performance, increasing efficiency, color purity, and stability, showcasing a sustainable dual-additive approach for optoelectronic applications.
