Abstract
Atomistic computer modelling and Extended X-ray Absorption Fine Structure (EXAFS) measurements were used to study the mode of solution and defects in Sr2+-doped La2O3. The computer modelling indicates that the most energetically favourable mode of solution is cation substitution with the formation of charge-compensating anion vacancies. This is confirmed by the EXAFS measurements. The EXAFS results also indicate that at high levels of Sr2+ there is the formation of the defect clusters with impurities and anion vacancies on adjacent sites, although the precise structure of the clusters could not be unambiguously identified.
