| Abstract: | The optical properties of TiO2 semiconductor ultrafine particles with surface modification was investigated, in contrast with those of bulk and naked TiO2 ultrafine particles. The experimental results show that the strong chemical interactions between the surface of the particles and the organic molecules has significantly changed their properties. |
