Fluorescent carbon nanoparticles were prepared by electrochemical methods using pyrolytic graphite as raw materials. The effects of lead ion solutions with different concentrations on light emission of carbon nanoparticles were systematically investigated and the roles of reaction time
pH values
and temperature played were also considered in this paper. Experimental results show that lead ions can change the intensity of photoluminescence (PL) from carbon nanoparticles rather than its spectral shape. The effects of lead ions on PL of carbon nanoparticles reduce with the increase of reaction time
and change with pH values. In addition
the higher temperature can strengthen the effects of lead ions on PL intensity of carbon nanoparticles. The possible mechanism could be attributed to charge transfer and Brownian movement.
