Abstract

Tuning to G(O) flat: Photoluminescence in graphene oxide (GO) suspensions can be tuned from red to blue emission (see scheme) by gradually changing the amounts of sp ²- and sp ³-bonded carbon atoms through reduction of the surface oxide groups. Electron-hole recombination from two different types of excited states is proposed to explain the luminescence in GO at varying degrees of reduction.
