Abstract

Multicore-shell CdS-Si02 nanoparticles were synthesized in AOT/heptane/H2O reverse micelles at room temperature. CdS-SiO2 nanoparticles were characterized by UV-vis spectroscopy, TEM, and SEM methods. The results show that multicore-shell composites were formed. Fluorescence properties of composites were also investigated; the data imply that fluorescence properties of the silica-coated CdS nanoparticles were significantly improved when compared to those of the non-coated CdS nanoparticles. The stability of multicore-shell CdS-SiO2 nanoparticles upon the UV irradiation was higher than that of non-coated CdS nanoparticles.
