This synthesis reports a 98.5% photoluminescence quantum yield and enhanced stability in sodium-indium perovskites, suggesting promising optoelectronic applications.
Two-dimensional double perovskite materials have emerged as promising environmentally benign alternatives to lead-based perovskites, exhibiting great potential for diverse optoelectronic applications. Herein, we report the first sodium-indium-based Dion-Jacobson double perovskite, (PDMA)2NaInCl8, synthesized via a high-pressure hydrothermal method, designed for light-emitting applications. The incorporation of PDMA organic cations not only confers unique blue-light emission but also endows the material with ultrahigh thermal and environmental stability. Upon Sb3+ doping, (PDMA)2NaInCl8 achieves a photoluminescence quantum yield of up to 98.5%—one of the highest reported for 2D double perovskites—highlighting its promise for high-performance fluorescent devices and anti-counterfeiting applications. This study provides valuable insights and guidance for the selection of organic amines in the design of novel lead-free layered perovskite systems.
