The general objectives of this project are:

  • To elaborate, evaluate and validate at laboratory level a technology for the synthesis of an innovative nonlinear optical material having optical limiting properties in visible and infrared domains.
  • To build a prototype device that incorporates the material showing the best performances.

The main specific objectives of the project are:

  • To develop surface functionalized, well dispersed graphene oxide (GO) and reduced graphene oxide (rGO) to obtain homogeneous, stable and reproducible suspensions for two optical nonlinear materials types: as GO/rGO based composite and as GO/rGO coating.
  • To develop a laboratory sol-gel synthesis technology for the preparation of graphene oxide silico-phosphate composites.
  • To develop an alternative laboratory sol-gel synthesis technology for GO and rGO films on glass/ITO substrate.
  • To explore the specific optical properties of the innovative graphene silico-phosphate composite materials, and innovative films of GO/rGO, prepared by sol-gel method, for laser damage prevention applications. The optical limiting functionality of the synthesized materials will be investigated by Z scan and I scan methods.
  • To build a prototype device that incorporates the best performing material and demonstrates the prevention of optical sensors (CCD, CMOS, etc.) damage by testing the device when exposed to high intensity laser beams.
