Abstract
The UV absorption spectra of F −3 molecular ions in LaF3, SrF2, CaF2, and BaF2 crystals doped with rare-earth elements are studied. Comparison of radiation-colored and additively colored crystals reveals the absorption bands of F −3 hole centers in the region near 6 eV. Nonempirical calculations of optical transitions agree well with experimental results.
