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