Research paper thumbnail of Probing the origin of fluorescence quenching of a graphene-porphyrin hybrid material

EPJ Web of Conferences, 2013

We report transient absorption spectroscopic studies on the hybrid material composed of porphyrin... more We report transient absorption spectroscopic studies on the hybrid material composed of porphyrin molecules covalently attached to graphene for investigating the mechanism underlying the reported fluorescence quenching of porphyrin in the hybrid [1]. Excited state dynamics of pure graphene suspension and porphyrin have also been studied as reference samples. A fast excited state decay was observed in the hybrid.
