摘要
As is known, the compounds containing Eu<sup>2+</sup> ions under ambient pressure are sosensitive to moisture and oxygen that they cause great diffculty in sample handling andmeasurement. In order to improve the Eu<sup>2+</sup> stability to a certain extent, we report in thisletter the stability, structure and fluorescence properties of EuI<sub>2</sub>,RbEuI<sub>3</sub>,RbEu<sub>2</sub>I<sub>5</sub> andRb<sub>3</sub>Eul<sub>5</sub> compounds under 20 kbar pressure.
