    • “金属卤化物钙钛矿材料因其独特的光电性质，成为发光二极管领域的研究热点。然而，钙钛矿表面及其与传输层的界面缺陷一直是制约器件性能与稳定性的瓶颈。针对这一问题，科学家们提出了一种创新的表面处理策略，即在萃取剂中添加乙酸胍。这一方法显著减少了钙钛矿层表面的缺陷，优化了薄膜形貌，使得钙钛矿薄膜的荧光量子产率从64%跃升至79%。基于这种优化后的钙钛矿薄膜制备的发光二极管，其最大效率高达11.66%，最大亮度达到1285 cd·m-2，性能远超未处理的参考器件（6.69%，689 cd·m-2），并且展现出更为优越的稳定性。这一研究成果为钙钛矿发光二极管领域的发展提供了新的动力，不仅提升了器件性能，更为其未来商业应用奠定了坚实的基础。”
