摘要

Perovskite quantum dots (PQDs) have excellent optical properties such as high photoluminescence quantum yield (PL QY) and high colour purity, and thus show promising application prospects in photoelectric devices. However, the poor stability of PQDs (especially red-emissive PQDs) greatly limits their applications. Herein, we synthesized CsPbBr_3-xI_x/ZnSe heterostructures via in-situ formation of ZnSe QDs in the red-emissive CsPbBr_3-xI_x PQDs, which maintains the high PL QY (∼70%) but greatly enhances the stability of PQDs. Subsequently, we utilized the red-emissive CsPbBr_3-xI_x/ZnSe heterostructures and green-emissive CsPbBr₃ PQDs as the light conversion materials to fabricate a QD film, which was then applied in backlight display with ultra-wide colour gamut up to NTSC 125%.
