We report broadband visible photoluminescence from solid graphene oxide, and modifications of the emission spectrum by progressive chemical reduction. The data suggest a gapping of the two-dimensional electronic system by removal of ฯ€-electrons. We discuss possible gapping mechanisms, and propose th
