摘要：
The interfacial electron transfer (IET) dynamics of single CdSe core/multilayer shell (CdS2MLZnCdS1MLZnS1ML) quantum dots (QDs) on the (110) surface of a rutile TiO2 single crystal and TiO2 nanoparticles have been compared. The fluorescence decay rates of single QDs on TiO2 are faster than those on glass, an insulating substrate, due to IET from the QDs to TiO2. Whereas the average IET rates are similar for QDs on the single crystal and nanoparticles, the distribution of IET rates is much broader in the latter, indicating a broad distribution of QD adsorption sites on the TiO2 nanoparticles.
