Dual-excitation and dual-emission carbon dots (CDs) have been prepared by simple one-step hydrothermal treatment of p-phenylenediamine and 5-aminosalicylic acid. The as-prepared CDs emit bright green fluorescence under excitation at 320–400 nm and bright orange fluorescence under excitation at 490–560 nm. Interestingly, the CDs can be employed as a dual-excitation and dual-emission fluorescent probe for Fe³⁺ detection in aqueous solution and living cells. Furthermore, the obtained CDs can function as a promising dual-excitation and dual-emission temperature sensor. Additionally, the CDs can be utilized for lysosomal targeting.

用于 Fe3+ 检测、温度传感和溶酶体靶向的双激发和双发射碳点

双激发和双发射碳点 (CD) 通过对苯二胺和 5-氨基水杨酸的简单一步水热处理制备。制备的 CD 在 320-400 nm 激发下发出亮绿色荧光，在 490-560 nm 激发下发出亮橙色荧光。有趣的是，CDs 可用作双激发和双发射荧光探针，用于水溶液和活细胞中的Fe ³⁺检测。此外，获得的CDs可以作为一种很有前途的双激发和双发射温度传感器。此外，CD 可用于溶酶体靶向。
