| Outline of Final Research Achievements |
Quantum dots (QDs) provide an attractive alternative sensitizer to organic dyes. There is a lack of fundamental studies of QD on conventional nanocrystalline TiO2 electrodes with much amount of heteroigeneity. We have shown the dependences of the optical absorption, the ground state energy level, and interfacial electron transfer dynamics on the size of CdSe QDs on single crystal rutile-TiO2. The expenential optical absorption tail indicates a decrease in structural disorder with increasing size. The ground state energy level of the CdSe QDs shows anisotropic, depending on the surface orientation of TiO2. The interfacial electron transfer rate constant decreases with increasing size and depends on the surface orientation of TiO2.
