摘要：

Hydrogen has been diffused into calcium fluoride crystals doped with Eu, Yb and other Rare Earths. The local mode absorption from H− ions has been measured before and after X‐ or γ‐irradiations and a detailed study has been made of the new electronic transitions of Yb3+ ions near 1 μm which appear after the irradiation. It is concluded that for Eu and Yb dopings, RE3+—H−(i) pairs are produced which are thermally unstable. In CaF2:Yb crystals, a second centre involving two hydride ions has also been identified.
