Industrial-Scale Fabrication of Mixed-Halide Perovskite Quantum Dots with High Comprehensive Performances for Red-Emitting Modules
The large-scale fabrication of mixed-halide perovskite quantum dots (QDs) with concurrently enhanced optical performances and stability remains a bottleneck for both fundamental science and industrial deployment. Herein, we demonstrate an industrial-scale synthesis of CsPbBr1.5I1.5 QDs encapsulated in a silica molecular sieve (MS) through a modified high-temperature solid-state strategy. Our study reveals that the higher chemical reactivity of cesium carbonate/lead halide precursors, compared to traditional cesium halide/lead halide, inhibits halide segregation in obtained CsPbBr1.5I1.5/MS composites and consequently boosts their optical performance (full width at half maxima of 29.2 ± 0.7 nm and photoluminescence quantum yield of 86.2 ± 2.2%). Comprehensive stability assessments confirm the robust durability of these CsPbBr1.5I1.5/MS composites against humidity, heating, light irradiation, and even mechanical stresses. Further, we demonstrate red-emitting modules based on these CsPbBr1.5I1.5/MS composites via polymer-compatible processing techniques, exhibiting potential applications in flexible wearable devices, wide color-gamut displays, and underwater illuminations.
