Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CASPeer-Reviewed Publication
Researchers have developed formamidinium (FA)-alloyed cesium lead iodide perovskite nanoplatelets that combine improvements in phase stability with linearly polarized red emission. By precisely controlling A-site composition and surface ligand interactions, the team achieved uniform, well-oriented superlattices that maintain optical performance under ambient conditions. This breakthrough provides a new route toward stable, directionally controlled light sources for advanced photonic and display technologies.
