Abstract

We successfully synthesized blue, green, and red CsPbX₃ QDs-codoped flexible films using a one-step electrospun strategy, followed by coating a strongly hydrophobic silicone resin on the surface of the films. The codoped flexible light-emitting films are resistant to water, thereby preventing anion exchange and significantly prolonging the lifetime of light emitters under ambient air conditions.
