Abstract:A series of high‐quality Cu‐doped Zn–In–S nanocrystals (d‐NCs) were prepared by a conventional hot injection process. The full‐visible spectrum emission from 480 to 648 nm can be easily achieved by adjusting the Cu doping concentration in the Zn–In–S system, but not by varying the ratio of In/Zn in the alloyed host material. After wrapping the ZnS shell around the Zn–In–S:Cu d‐NCs core, the resultant Zn–In–S:Cu/ZnS core/shell d‐NCs not only exhibited an enhanced prominent photoluminescent quantum yield (PLQY) … 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.
