Abstract:We report on studies that demonstrate how the chemical
composition
of the surface of copper nanoparticles (CuNPs) – in terms of
percentage copper(I/II) oxides – can be varied by the presence
of N-donor ligands during their formation via laser ablation. Changing
the chemical composition thus allows systematic tuning of the surface
plasmon resonance (SPR) transition. The trialed ligands include pyridines,
tetrazoles, and alkylated tetrazoles. CuNPs formed in the presence
of pyridines, and alkylated tetrazoles ex… 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.
