The dynamics of CdTe quantum dots (QDs) clustering in water solutions in the presence of metal ions (Pb2+, Cr3+) is investigated. The data were obtained using absorption and fluorescent spectral analysis and fluorescent lifetime analysis. We observed that in the presence of lead ions CdTe QDs tend to form stable clusters of certain size. The results provide evidence of energy transfer between CdTe QDs inside formed clusters.
