INSTM 2007Perugia

Nanostructured glasses and polymers for advanced sensors:

synthesis and properties

INSTM 2007Perugia

Aim of the project

• preparation and characterization of nano-structured amorphous materials (glasses and polymers with nano-clusters or nanotubes)

• applications in the fields of poling-based devices and of Surface Plasmon Resonance (SPR) based sensors.

Who does what:• Torino: metal nanocluster doped silica thin films and thermal

poling on each sample. • Milano : measurement of non-linear optical properties; laser

poling• Napoli : preparation of glasses containing high polarizable

cations; electrical characterization of samples• Perugia : synthesis and characterization of nanostructured

polymers based on carbon nanotubes for non linear optical applications
