Interest in graphene based materials is high because of their unique mechanical and electrical properties.  These properties can be tuned or modified to create many novel materials.  The possible applications include sensors, transistors, solar cells, touch panels, etc.  Luminescence of graphene oxide has been studied, however success has been limited by a lack of uniformity in the treatment techniques and the inability to make strongly luminescent materials.  In an effort to create a highly luminescent graphene material, have the ability to probe binding sites, and provide selectivity for chemical targets, luminescent lathanides (europium and terbium) have been complexed with graphene-oxide.  The co-ordination of the lanthanide with the graphene-oxide was verified by laser induced fluorescence as well as SEM and TEM.  Molecular modeling of the complexes were also conducted to provide a better understanding of the surface interactions and provide future directions.
