作为传统显示器强有力的竞争者之一,量子点发光二极管(QLED)在显示领域备受关注。然而,高性能蓝光QLED器件的发光材料中通常含有镉或铅,这两类重金属有毒元素对人体健康和生态环境不利,也阻碍了QLED器件的规模化商用进程。因此,高质量无镉无铅型蓝光量子点材料的研发成为推动新型显示产业发展的动力和业界迫切追求的目标。历经数十年发展,InP和ZnSe等无镉无铅量子点材料的蓝光发射性能已取得较大进步,随着合成策略及蓝光材料的进一步优化改进,环境友好型蓝光量子点发光二极管器件性能有望追上传统红、绿光量子点器件的步伐。本文分别从合成优化手段、表面包覆策略、核壳结构类型、发光性能参数等方面进行汇总,系统综述了当前无镉无铅型蓝光InP和ZnSe量子点材料的研究进展,指出了QLED蓝光材料未来的发展方向。
As one of the strong competitors of traditional displays, quantum dot light-emitting diodes (QLED) have attracted much attention in the display field. However, the luminescent materials of high-performance blue QLED devices usually contain cadmium or lead which are toxic and harmful to human health and the ecological environment, and also hinder the large-scale commercial process of QLED devices,therefore, the research and development of high-quality cadmium-free and lead-free blue quantum dots have become the driving force to promote the development of new display industry and the industry’s urgent goals.After decades of development, the blue-emitting performance of cadmium-free and lead-free QDs such as InP and ZnSe has made great progress. With the further optimization and improvement of synthesis strategies and material compositions, the performance of environment-friendly blue-emiting QLED devices is expected to catch up with the pace of traditional red and green QLEDs. In this paper, the current research progress of cadmium-free and lead-free blue-emitting InP and ZnSe quantum dots are systematically summarized including the synthesis optimization methods, surface coating strategies, core-shell structure types, luminescence performance parameters and other aspects. Finally, the future development direction of QLED based blue-emitting materials is pointed out.
