Narrowing the Phase Distribution of Quasi‐2D Perovskites for Stable Deep‐Blue Electroluminescence

Abstract Solution‐processed quasi‐2D perovskites contain multiple quantum wells with a broad width distribution. Inhomogeneity results in the charge funneling into the smallest bandgap components, which hinders deep‐blue emission and accelerates Auger recombination. Here, a synthetic strategy applie...
