Abstract:The objective of this work was comparing the optical performance of hydrothermally and solvothermal synthesized unique florescent carbon quantum dots (FCQDs) from organic material and use it as a fluorescent ink for one of the significant information encryption applications. The goji berry and sucrose were used as a carbon source of experiment. FCQDs obtained by simple hydrothermal and solvothermal methods by using water, isopropanol and acetone as a solvent. The crystal structure and optical properties of th… 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.
