Ambient-Pressure Synthesis of SHG-ActiveEu2Ti2O7 with a [110] Layered PerovskiteStructure: Suppressing Pyrochlore Formation byOxidation of Perovskite-Type EuTiO3
Gram-scale quantities of Eu2Ti2O7 with a [110] layered perovskite structure have been synthesized at ambient pressure by thermally oxidizing (750−900 °C) perovskite-type EuTiO3. Eu2Ti2O7 is type 1 phase matchable and shows a SHG efficiency of 80 × α-SiO2.
