Abstract
Herein, nitrogen-doped CDs (NCDs) were synthesized in a hydrothermal microwave-assisted pyrolysis using citric acid and urea. Differing carbon-to-urea molar ratios were used and the pH-dependent fluorescence and quantum yield (QY) at various pHs were measured. All NCDs demonstrated pH-dependent fluorescence with increased fluorescence from pH 1-13. Overall, the NCDs with a carbon-to-dopant molar ratio of 1:6 demonstrated the highest QY of 19% in pH 11. Additionally, high quantum yields were observed between pH 7-11. Therefore, NCDs, as prepared, may serve as cost-effective fluorescent pH sensors or in bioimaging applications.
期刊介绍:
Sensors and Actuators Reports is a peer-reviewed open access journal launched out from the Sensors and Actuators journal family. Sensors and Actuators Reports is dedicated to publishing new and original works in the field of all type of sensors and actuators, including bio-, chemical-, physical-, and nano- sensors and actuators, which demonstrates significant progress beyond the current state of the art. The journal regularly publishes original research papers, reviews, and short communications.
For research papers and short communications, the journal aims to publish the new and original work supported by experimental results and as such purely theoretical works are not accepted.
