A rapid and energy efficient microwave assisted solid state preparative route for europium-doped Åkermanite (Ca2MgSi2O7) has been developed. This method reduces the reaction time and energy needed by more than 90%, compared to the preparation carried out in a conventional furnace. The obtained sampl...
