Area of Science:

  • Materials Science
  • Nanotechnology
  • Chemistry

Background:

  • Graphene oxide (GO) is an atomically thin graphite derivative with oxygen-containing functional groups.
  • GO possesses a mix of sp2- and sp3-hybridized carbon atoms, influencing its properties.

Purpose of the Study:

  • To review recent advances in the optical properties of chemically derived GO.
  • To explore new physical and biological applications of GO.

Main Methods:

  • Manipulation of sp2-hybridized domain size, shape, and fraction via reduction chemistry.
  • Controlled deoxidation to tune optoelectronic characteristics.

Main Results:

  • As-synthesized GO is insulating; controlled deoxidation yields transparent, conducting, and optically active material.
