摘　　要：量子点作为一种理想的发光材料,一直以来引起了科学家和工业界的广泛关注,推动了生物成像、照明、显示等领域的发展。随着生态环境保护的意识逐渐增强,磷化铟量子点(InP QDs)作为镉基量子点的最好替代者之一,受到了广泛的关注:一方面,InP QDs具有与镉基量子点相媲美的发光和光电性质;另一方面,其发光光谱范围可覆盖整个可见光区,且合成工艺与镉基量子点共通。然而,因为InP QDs与传统镉基量子点相比,在元素价态、核壳晶格匹配性、反应动力学过程等方面具有特殊性,其合成化学的发展还不成熟,限制了其光电应用的研究进程。本文结合量子点显示的发展现状和未来需求,针对InP QDs体系进行了综述,通过分析其研究现状,分析其发展问题和挑战,并对其进行了展望,期望为量子点及其电致发光器件的进一步探索研究提供一些启示和帮助,推动无镉、低毒、高色纯度量子点体系的发展。Quantum dots(QDs),as an ideal light-emitting material,have been attracting a lot of attention from scientists and industry,advancing the development of bio-imaging,lighting,display and other fields.With the gradu‐al increase in awareness of ecological and environmental protection,indium phosphide quantum dots(InP QDs)have received widespread attention as one of the best alternatives to cadmium-based quantum dots.On the one hand,InP QDs have luminescence and photovoltaic properties comparable to those of cadmium-based quantum dots.On the other hand,their luminescence spectral range can cover the entire visible region,and their synthesis process is com‐mon to that of cadmium-based quantum dots.However,as InP QDs are special in terms of elemental valence,core-shell lattice matching and reaction kinetics compared to traditional cadmium-based QDs,the development of their synthetic chemistry is still immature,which limits the research process of their photovoltaic applications.Here,we review the indium phosphide QDs system on its development and future needs for displays,by analyzing the current status,problems,challenges,and making an outlook on it.We expect to provide some insights and help for further exploratory research on QDs and their electroluminescent devices(QLEDs),and to promote the development of cad‐mium-free,low-toxicity,high-colour purity QDs system.
