Abstract
Water-soluble CdTe nanocrystals (NCs) were synthesized and applied to study the effect of metal ions on chemiluminescence (CL) of the CdTe/H 2O 2 system. The effects of experimental factors, such as pH, particle sizes of CdTe and reagent concentration, on kinetics curve and CL intensity of the CdTe/H 2O 2 system were examined. The results showed that under the optimal conditions Ba 2+, Ca 2+, Fe 2+, Pb 2+ and Cu 2+ enhanced the CL intensity, and Cr 3+, Ni 2+, Zn 2+ and Ag + inhibited the CL intensity.
