Analysis of the luminescence properties of Eu 3+ in Li,Eu(BOz)X suggests that the energy migration which occurs over the Et?+ sublattice down to low temperatures is one-dimensional. The temperature dependence of the migration points to a two-site nonresonant two-phonon assisted process. It occurs by exchange interaction.
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.
