[14p-C31-7] Femtosecond laser multi-photon reduction in TiO2 nanoparticle dispersed solution

Keywords:femtosecond laser, multi-photon reduction, titanium oxide

We report femtosecond laser multi-photon reduction in silver nitrate solution with TiO2 nanoparticles. Doping of TiO2 nanoparticle into the solution strongly enhanced precipitation volume because of their high photo-activity. Optical observation revealed that the precipitation occurred not only the focal point but also the surroundings. In this presentation, we show the effects of laser irradiation conditions on size of the precipitated structures.
