Template-capped TiO 2 nanostructures have been synthesized. In certain template conditions, TiO 2 hexagons are found to form. These hexagonal structures can be effectively sensitized by fluorescein dye without any change in the protonation state of the dye. Bare TiO 2 nanoparticles are not so useful for sensitization with dyes like fluorescein as they alter the dye protonation state. The novelty of this work is twofold—the hitherto elusive hexagonal phase of TiO 2 nanoparticles has been stabilized and the synthesis of TiO 2 in the rutile phase has been achieved under mild conditions.
