Schematic diagram of the excited state proton transfer from dye molecules to the titania surface, fluorescence process and energy level diagram

Caption

When the titania surface and the dye adsorbed on its surface are irradiated with ultraviolet light, the proton transfer occurs from the excited states of the dye molecules to the titania surface where basic hydroxyl groups are generated and fluorescence is observed from the excited states of the deprotonated dye.
