Quenching of graphene suspension photoluminescence with saturated hydrocarbons
Source abstract
Abstract
Abstract This paper describes a study of quenching of graphene suspension (GS) photoluminescence upon formation of an interphase interface by a saturated hydrocarbon using n-octane (С8Н18) as an example. Based on the analysed photoluminescence spectra, structural analysis, and theoretical evaluations, the paper offers a model where octane molecules are attached at the edges of composite graphene sheets by the presence of functional oxygen-containing groups. It is assumed that in the formed structure quenching of photoluminescence relates to the Anderson electron density delocalisation effect.
