以柠檬酸铵、NH3· H2O和H2O2为前驱体，采用简单的水热法直接合成了具有上转换特性的强绿色荧光碳点。合成的绿色荧光CD也显示出优异的上转换特性，并且可以直接用于活HeLa细胞成像而无需任何进一步的修饰。
The strong green fluorescent carbon dots (CDs) with the upconversion property have been directly synthesized using ammonium citrate, NH3· H2O, and H2O2 as the precursors in aqueous solution through a simple hydrothermal process. The synthesized green fluorescent CDs also show excellent upconversion property and can be directly used for live HeLa cell imaging without any further modifications.
