Abstract

Controlling CsPbX₃ (X = Cl, Br, I) nanocrystal growth is challenging due to subsecond ionic metathesis. Here, spatial confinement at the hexane–acetonitrile interface enables precise control of kinetics, achieving ultra-wide PL tunability (434–520 nm for CsPbBr₃, 541–662 nm for CsPbI₃) from blue-violet to green and yellow-green to deep red.
