Abstract

Electron injection from photoexcited dye molecules into semiconductor colloidal particles (TiO2 and ZrO2) is investigated by femtosecond (fs) spectroscopy. Ultrafast reaction dynamics in the dye/ZrO2-system with an inaccessible conduction band demonstrates efficient electron transfer to surface defect states.
