Currently, the synthesis of carbon dots (CDs) exhibiting long-wavelength emission is still challenging. Herein, we have synthesized for the first time three types of CD with multicolor emission derived from isomers. Importantly, their particle size, nitrogen-doping amount and band gaps collectively regulate the fluorescence emission of the proposed CDs.

探索源自异构体的三种类型的多色碳点†

当前，展现出长波长发射的碳点（CD）的合成仍然具有挑战性。在本文中，我们首次合成了三种类型的CD，其具有源自异构体的多色发射。重要的是，它们的粒径，氮掺杂量和带隙共同调节了所提出的CD的荧光发射。
