Air-stable and water-resistant all-inorganic perovskite quantum dots films for white light-emitting applications

Abstract

All-inorganic perovskite quantum dots (PeQDs) attracted much attention recently due to their great illumination properties, however the instability of PeQDs restricted their application. In this work, we successfully synthesized CsPbX3 (X = Br, I) PeQD/Ergo films by encapsulation of PeQDs within Ergo® optical adhesive 8500 (Ergo 8500). The CsPbX3 PeQD/Ergo films exhibited great water-resistance and air-stability. The photoluminescence of the films kept stabilizing for weeks in water and months in air. By trying different structures and PeQDs volumes, CsPbX3 PeQD/Ergo white LEDs (WLED) were successfully fabricated. The CsPbX3 PeQD/Ergo W-LED exhibited high quality white light with the CIE color coordinate of (0.3692, 0.3442) and correlated color temperature of 4059 K.
