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.
