Synthesis of single-layer graphene-quantum dots nanocomposite directly from graphene oxide

Graphene is currently one of the hottest materials, its excellent electrical conductivity and its thin flexible two-dimensional feature make it a superior component for nanocomposite materials, for example being a transparent window electrode for dye-sensitized solar cells. However, one of the biggest obstacles to graphene research is to obtain single-layer graphene in large quantity. We reported here a simple strategy to fabricate graphene-quantum dots nanocomposite via a facile one step reaction from the soluble graphene oxide, this approach avoids the above obstacle by skipping the graphene production step, and may be used to fabricate other graphene nanocompistes.
