摘要
CdS nanoclusters were directly synthesized in aqueous solution by using mercaptoacetic acid as the stabilizer. The results of TEM(Transmission Electron Microscopy) and ED(Electron Diffraction) show that the structures and aggregations of the resulting CdS nanoclusters can be affected by the molar ratio of mercaptoacetic acid and Cd 2+ ion. When the ratio was high, the resulting nanoclusters were observed as densely packed layer structure on the template. When the ratio was low, the prepared CdS nanoclusters can not form highly aggregated structure. Fluorescence spectra of the CdS nanoclusters show a strong yellow fluorescence.
