摘      要：The past decade has witnessed a variety of members of the carbon family along with exposure of carbon dots due to their magnificent properties in sensing,bioimaging,catalytic applications,biomedical fields,and so ***,we report the simple hydrothermal method to fabricate photoluminescent doped carbon quantum dots for the detection of noxious lead(II)***(II)ion is very venomous for both the environment and human health for which its detection is demanded area in the research *** as-prepared carbon dots show excellent photostability,low toxicity and significant photoluminescence properties along with good water *** with these properties,carbon dots have a quantum yield of approximately 15%.In the practical field of application,these carbon dots have been used as sensing probes for the detection of lead(II)ions with a detection limit of 60 nmol·L^(–1).The fluorescence intensity of carbon dots was remarkably quenched in the presence of the lead(II)ion selectively among all the tested metal ***,we have studied the Stern–Volmer relationship for lead(II)quenching along with the explanation of the probable quenching *** of the doped carbon dots in heavy metal ions sensing in an environmental sample was demonstrated.
