Abstract

We report a novel strategy for the preparation of CsPbBr₃ perovskite quantum dots by polyacrylic acid-b-polystyrene ligands, which exhibited high stability and photoluminescence quantum yields. The fabricated white light-emitting diodes exhibited luminescence performance with the colour rendering index of 65.5, and a correlated colour temperature of 5464 K.
