Synthesis and Characterization of Silver Nanoparticles Coated Titanium Dioxide Nanowires

Abstract:

For the sake of investigating the special optical character of heteronanostructures, we grow TiO2 nanowires following a three step synthesis method and coat silver nanoparticles on these nanowires with replacement method. Firstly, by adjusting the experiment parameters, we get the single crystalline titanium dioxide nanowires and control their length and diameter successfully. Secondly, we use the replacement method to make the silver nanoparticles coated on these nanowires. Finally, we use transmission electron microscopy and X-ray diffraction to characterize these productions and the results show that the silver nanoparticles are coated on the titanium dioxide nanowires uniformly and the components of these nanowires are only sliver and titanium dioxide. These new optical heteronanostructures are widely investigated all over the world and we sure that they can make great influences to the development of nanophotonics.
