Indoleacetic acid-mediated suppression of oxidation and crystallization in tin perovskite LEDs

Key Points

• The aim is to investigate how indoleacetic acid affects oxidation and crystallization in tin perovskite LED materials.
• Synthesize two-dimensional organic-inorganic hybrid tin-based halide perovskites.
• Introduce indoleacetic acid as an additive.
• Evaluate the impact on material properties through various characterization techniques.
• Indoleacetic acid significantly reduces oxidation in the materials.
• Crystallization of tin perovskites is suppressed, leading to improved stability.
• Enhanced photoluminescence confirms higher color purity in the LEDs.
