Zusammenfassung:In article number 2300486, Jae‐Wook Kang, Jeong‐Hwan Lee, and co‐workers employ a short‐chain fluoroaromatic ligand, 4‐fluoro‐phenethylammonium bromide, to fine‐tune the refractive index (n) and horizontal dipole ratio values (ΘH) of FAPbBr3 nanocrystal film for light outcoupling efficiency enhancement. This work demonstrates that the performance of perovskite light‐emitting diodes can be greatly enhanced via optical engineering.
