▎ 摘　　要

A new hybrid material, graphene oxide-Resorcinol (GO-R) is synthesized from graphite following the modified Hummers method, characterized and utilized as a fluorescent chemosensor to detect Cerium ion under aqueous conditions. The effect of pH, reversibility, time and the interference of other potentially competing ions have been studied. The sensing follows both the photo induced electron transfer and intramolecular charge transfer processes. (C) 2018 Elsevier B.V. All rights reserved.
