Blue photoluminescene (PL) from chemically derived graphene oxide has been observed . The PL is attributed to radiative recombination of electron–hole pairs in isolated “molecular” sp 2 domains, which are present within the carbon–oxygen sp 3 matrix in chemically derived graphene oxide. The PL intensity is correlated to the evolution of sp 2 domains during reduction.
