A simple and general synthetic approach for one-step creation of graphene-upconversion nanocomposite by an in situ hydrothermal method has been developed. Using graphene oxide (GO) as a precursor reagent, the reduction of GO and the deposition of NaYF4/Yb, Er on graphene occur simultaneously. The electrogenerated chemiluminescent intensity of NaYF4/Yb, Er is significantly amplified by graphene due to its wonderful conductivity, extraordinary electron transport properties and large specific surface area.
