摘      要：Nitrogen-doped carbon dots(N-CDs) were hydrothermally synthesized by folic acid, which revealed excited wavelengtli-dependent blue emission and the specific recognition ofHg ions by fluorescence quenching. A wide range response and a fitted linear relationsliip for Hg ions detection were established to show that tliese blue-emission N-CDs achieved a satisfying Hg ions detection in Chinese traditional herb, Rannasaiigpei(RSNP). Tlie 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.
