**氟化亞銪**是一種無機化合物，化學式為 EuF2。它首次於 1937 年被合成。

## 製備

氟化亞銪可由氟化銪和金屬銪或氫氣反應得到：

　
: $\mathrm {2\ EuF_{3}+Eu\longrightarrow 3\ EuF_{2}} $

　
: $\mathrm {2\ EuF_{3}+H_{2}\longrightarrow 2\ EuF_{2}+2\ HF} $

## 性質

氟化亞銪是亮黃色的固體，它具有螢石結構。在 114 kPa 的壓力和 400 °C 下，它轉變為正交的氟化鉛型晶體。它在常溫的空氣中穩定，高溫下活潑，易和氧反應，生成 EuOF 等產物。
