摘要

Nitrogen-doped carbon dots(N-CDs) were hydrothermally synthesized by folic acid,which revealed excited wavelength-dependent blue emission and the specific recognition of Hg ions by fluorescence quenching.A wide range response and a fitted linear relationship for Hg ions detection were established to show that these blue-emission N-CDs achieved a satisfying Hg ions detection in Chinese traditional herb,Rannasangpei(RSNP).The results from the N-CDs FL quenching gave the similar outcomes with those from ICP-OES measurement,which exhibited the possibility of the simple FL method of Hg ions detection by N-CDs in Chinese traditional herbs.
