Abstract:Stoichiometric rare-earth materials
have demonstrated extremely
narrow inhomogeneous photoluminescence-excitation linewidths because
the rare-earth cations occupy uniform crystallographic sites. These
narrow linewidths make them strong candidates for quantum information
storage by providing access to transitions with extremely long coherence
times on the order of hours. Determining the chemical origins of defects
that may broaden linewidths and reduce performance is an important
step toward exploiting stoichio… 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.
