Abstract

Solution-processable colloidal quantum dots (QDs) are regarded as promising light emitters for next-generation displays owing to their high photoluminescence quantum yield (PLQY) and broad color tunability. Even though cadmium (Cd)-based QDs and relevant electroluminescent light-emitting diodes (LEDs) progressed rapidly, their commercial deployment remains prohibited due to potential environmental concerns. In this review, recent advances in synthesizing eco-friendly, bright, and color-pure emitting QDs including InP, ZnSeTe, and AgInGaS₂ (AIGS) QDs toward high-performing LEDs are presented. In particular, the synthetic strategies such as regulating the composition, core/shell structure, and surface ligands of QDs for enhancing the PLQY and reducing the spectral bandwidth are comprehensively discussed. Moreover, various techniques to obtain high-performance QDs-based LEDs (QLEDs) involving device architecture and interface engineering as well as modification in electron and hole transport layers are overviewed. Finally, the existing challenges and outlook regarding the optimization of QD's synthesis and optical properties for boosted QLEDs device performance are put forward to enable prospective advanced displays.

环保型胶体量子点及其在发光二极管中应用的进展：为显示器实现明亮、色彩纯正的发光效果

可溶液加工的胶体量子点（QDs）因其高光致发光量子产率（PLQY）和广泛的色彩可调性，被视为下一代显示器的理想发光体。尽管以镉（Cd）为基础的 QDs 和相关的电致发光发光二极管（LEDs）发展迅速，但由于潜在的环境问题，其商业应用仍被禁止。本综述介绍了在合成环保、明亮、颜色纯正的发光 QDs（包括 InP、ZnSeTe 和 AgInGaS2 (AIGS) QDs）以实现高性能 LED 方面的最新进展。特别是全面讨论了调节 QDs 的组成、核/壳结构和表面配体等合成策略，以提高 PLQY 并降低光谱带宽。此外，还概述了获得基于 QDs 的高性能 LED（QLED）的各种技术，包括器件结构和界面工程以及电子和空穴传输层的改性。最后，就如何优化 QD 的合成和光学特性以提高 QLEDs 器件性能提出了现有的挑战和展望，以实现未来的先进显示技术。
