Abstract:Herein we report a simple fabrication of graphene and titanium dioxide nanotube composite using hydrothermal method. Photoluminescence emission of the composite were investigated to study defect states in bandgap of nanotubes when the content of graphene varied from 1 wt% to 8 wt%. With the content of graphene lower than 5 wt%, the photoluminescence spectra form of the composite showed similar to that of pristine titanium dioxide nanotube. When the content of graphene reached 8 wt%, the emission positions were… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
