Effects of TiO2 shells on optical and thermal properties of silver nanowires

A simple and efficient coating method of silver nanowires with uniform shells of TiO2 has been
established using 2-mercaptoethanol monolayers. The thickness of the titania coating layer can be
controlled by changing the concentration of the precursor solution. In situ TEM thermal annealing
studies showed that the silver nanowire core remains intact until temperatures of 750 C, which is
significantly higher than the melting temperature of the bare silver nanowires. After this temperature,
the Ag nanowires were melted and subsequently vaporized, leaving TiO2 nanotubes. The effects derived
from the growth of titania shells on the optical properties of silver nanowires have been investigated as
a function of the shell thickness. The surface plasmon resonance mode of these nanowires undergoes
a gradual red shift and decreases in intensity upon systematic build-up of the dielectric cover

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
