Nanopatterns of a TiO2-organic hybrid material have been fabricated with the use of a localized surface plasmon (LSP). The TiO2-organic hybrid material was prepared by the sol-gel method and was coated on a glass substrate with gold nanoblocks. After the hybrid films were irradiated with a femtosecond laser, the unreacted parts were removed, leaving the TiO2-organic hybrid materials around the nanoblocks. In the nanopatterns of the TiO2-organic hybrid materials, the pi - pi* transition absorption band of the chelate compound formed between Ti-alkoxide and beta-diketone was excited by the two-photon absorption induced by the LSP of gold nanoblocks, and the chelate compound was decomposed and dissolved in alcohol. It was confirmed that the hybrid material changed to anatase upon sintering above 450 degrees C.
