Use of long-term stable CsPbBr₃ perovskite quantum dots in phospho-silicate glass for highly efficient white LEDs

We report the synthesis of CsPbBr₃ QDs with great stability and high quantum yield in phospho-silicate glass, which was fabricated by using a heat-treatment approach, for white light emitting devices. QD glasses exhibited excellent photo- and thermal stability, and significantly prolonged the lifetime of light emitters under ambient air conditions.
