摘要：

The composition of TiO2 and aqueous CdTe nanoparticles were prepared via sol-gel method. The morphology and structure of the CdTe@ TiO2 composite nanoparitcles were characterized by SEM and TEM instruments and their mechanism of formation was proposed. The investigation of their photoluminescence(PL) properties show that the PL intensity of CdTe nanoparticles become weaker than their parent aqueous solution. These composite nanoparticles exhibit similar fluorescence lifetime, which is shorter than those in the aqueous solution. These experimental results indicate that the CdTe@ TiO2 composite nanoparticles have potential application in the filed of solar cells.
