Grafeenioksidi on grafeenin hapettunut muoto, jossa levyn pintaan on liittynyt funktionaalisia happiryhmi\u00e4. Grafeenioksidilla on havaittu laaja luminesenssi, joka riippuu sen hapetusasteesta, pH:sta, viritysaallonpituudesta ja konsentraatiosta. Luminesenssin on arveltu aiheutuvan mm. grafeenioksidin sp2-alueista kvanttirajoituksen takia.
