Abstract
Calcium fluoride (CaF2), like the important UO2 phase, is a defect system having the remarkable property that large concentrations of trivalent rare-earth dopants can be accommodated within its structure with no loss of structural integrity. Using extended X-ray absorption fine structure (EXAFS), we have observed the way in which the local structural environment of the impurity alters with the size of the rare-earth ion and can distinguish, by computer lattice simulation studies, between dimer and hexamer configurations for light and heavy dopants, respectively.
