Water-resistant luminescent polymer composites with CsPbBr3 quantum dots in Cs4PbBr6 crystals (CsPbBr3@Cs4PbBr6) are reported. These color-converting materials enable a narrow-band green emission with fast dynamics and are therefore a potential alternative to phosphors, mainly for applications that require a fast modulation of light.
