Photoluminescent bimetallic-3-hydroxypicolinate/graphene oxide nanocomposite

abstract

A new photoluminescent bimetallic-3-hydroxypicolinate/graphene oxide composite was prepared by incorporation of the complex Na-5[EuW2O6(picOH)(8)] (1; HpicOH being 3-hydroxypicolinic acid) on graphene oxide (GO). Photoluminescence studies (emission and excitation spectra and D-5(0) emission decay curves) were performed on 1 and the composite 1/GO suggesting an effective interaction between the picOH(-) ligands and the graphene oxide.
