A new class of phosphors is described based on alkaline earth halophosphates possessing spodiosite and apatite structures as host matrices for lanthanide ion activators. The materials are presented in terms of the formulations used for their synthesis; these formulations have pronounced effects on efficiency and spectral properties of the final compositions. Divalent europium is the principal activator considered.
The luminescence of Yb2+ in alkaline earth phosphates and vanadates is reported. Particular attention has been given to those compositions possessing apatite and spodiosite structures. Emissions from Yb2+ are broad and sensitive to host composition. Single and double emission bands are observed which exhibit a variety of temperature dependent relationships. The decay of the Yb2+ fluorescence, under cathode‐ray excitation, is short.
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.
