In article number 2102006, Jason D. Slinker and co‐workers leverage CsPbBr 3−x Cl x perovskites, polyelectrolytes, and a salt additive to demonstrate pure blue emission from single‐layer light‐emitting electrochemical cells. The electrolytes transport the ions from salt additives, enhancing charge injection and stabilizing the inherent perovskite emissive lattice for highly pure and sustained blue emission. The resulting pure blue emission meets the US NTSC blue standard benchmark.
