Abstract
Compared with the conventional analytical approaches exploited for environmental pollutant assessment, the fluorescent sensing strategy has pronounced advantages, including rapidity, simplicity, and efficiency. Fluorescent carbon dots (CDs) are a class of carbon-based architectures. CDs are well-defined ultra-small-sized architectures that are formed by a few to a hundred carbon atoms and display high fluorescence behaviors. Nowadays, CDs are often used as fluorescent sensors for environmental pollutant assessment. This chapter aims to focus (from 2015 to 2022) on the recent improvements in the use of CDs for environmental pollution assessment such as heavy metal ions, pesticides, antibiotics, and bacteria. In addition, we have summarized the progress of research on CDs regarding their synthesis from small organic molecules and green materials.
