摘要
碳点由于其低毒性、易制备、良好的光稳定性及可调的发光等特性有望成为一类理想的新型固态发光材料。然而,由于聚集诱导荧光猝灭(ACQ)效应的存在,使得碳点在固态发光领域的发展受到了限制,因此制备具有抗ACQ效应的固态发光碳点是碳点研究领域的一个重要方向。本文根据固态发光碳点研究的最新进展,从碳核、表面态调控、超分子及聚合物交联增强发光方面分类总结了具有抗ACQ效应固态发光碳点的制备方法及光物理性质,探讨了其实现固态发光的物理机制。此外,还介绍了该类碳点在固态发光领域的应用进展,并对固态发光碳点的发展现状和所面临的问题进行了讨论。
Because of their low toxicity,easy preparation,good photostability and color-tunable photoluminescence,carbon dots are expected to be a new kind of ideal solid-state photoluminescent materials.However,due to the aggregation-induced fluorescence quenching(ACQ)effect,the development of carbon dots in the field of solid-state photoluminescence is limited.Preparing solid-state emissive carbon dots featuring anti-ACQ ability is an important topic in the field of carbon dot research.On basis of the latest progress in the study of solid-state emissive carbon dots,this review summarizes the synthesis and photophysical properties of these carbon dots with anti-ACQ ability in terms of core/surface state controlling and supramolecular/polymer crosslink-enhanced emission,and discusses the physical mechanisms for the occurrence of the solid-state emission.Moreover,the application progress of these carbon dots in the field of solid-state photoluminescence is introduced,and the current situation and problems they faced are discussed.
