Converting a layer perovskite into a non-defective higher-order homologue: topochemical synthesis of Eu2CaTi2O7
Abstract
Topochemical reduction of CaEu2Ti2O8, a new n=1 mixed Ruddlesden–Popper/Dion–Jacobson phase prepared by divalent ion-exchange of NaEuTiO4, yields the non-defective n=2 Ruddlesden–Popper phase Eu2CaTi2O7.
