摘要:

碳点(CDs)作为一种光学性能优异的零维碳纳米材料, 在光电器件及生物成像等领域得到了广泛的应用. 然而, 固态CDs由于聚集造成的共振能量转移和π-π堆积会导致固态发光猝灭, 极大阻碍了其在荧光粉或固态照明等方面的应用. 因此, 研究人员探索了多种获得固态发光CDs的方式. 本文综合评述了CDs固态发光的机理和现阶段常用的合成策略, 介绍了固态发光CDs最新的应用领域,最后指出了制备固态发光CDs面临的困难和挑战.

Abstract:

As a 0-dimensional carbon nanomaterial with excellent optical properties, carbon dots(CDs) has been widely used in optoelectronic devices, biological imaging and other fields. However, due to the resonance energy transfer and π-π accumulation caused by the aggregation of solid CDs, the solid emission quenching has greatly hindered its application as phosphors. So the researchers explored a variety of ways to obtain solid-state luminescent CDs. In this paper, the mechanism, classification and research progress of solid-state luminescence CDs are reviewed, and the latest application fields of solid-state luminescence CDs are introduced. Finally, the difficulties and future challenges in the preparation of solid-state luminescent CDs are presented.

Key words: Carbon dots, Solid state luminescence, Fluorescence, Afterglow
