“…Our data show that MF 2 is a cleaner system for testing conceptual issues than oxides due to their 4 extreme ionic status 29 . Additionally, MF 2 was only marginally studied 8,12,[26][27][28]30 . There are still controversial questions on the type of insulators for the higher members in the series 2,8,30 , on the understanding of the Fluorine XES lineshape 26,28,31 , and on the irregular variation of the leading edges of XAS spectra 26,27 .…”

We report the most direct experimental verification of Mott-Hubbard and Charge-Transfer insulators through X-ray emission spectroscopy in transition-metal fluorides. The p-d hybridization features in the spectra allow a straightforward energy alignment of the anion-2p and metal-3d valence states, which visually shows the difference between the two types of insulators. Further, in parallel with the theoretical Zaanen-Sawatzky-Allen diagram, a complete experimental systematics of the 3d Coulomb interaction and 2p-3d charge-transfer energy is reported, and could serve as a universal experimental trend for other transition-metal systems including oxides.

With a high-resolution two-crystal vacuum spectrometer, the fluorine Kα emission spectra in fluorescence are measured for AlF3, CrF3·xH2O, FeF3·xH2O, NiF2·4H2O, ZrF4, NH4NbF6 and a series of rare-earth trifluorides RF3 (R=La, Ce, Pr, Nd, Sm, Eu and Gd). The measured emission spectra consist of a prominent peak and its high-energy satellites. It is shown that the presence of the K1L1 satellite peak arising from the 1s-1 2p-1 initial state is unclear in LaF3, CeF3, PrF3 and NdF3, in contrast to that of other metal fluorides. This unclear presence is attributed to the F 2p shell vacancy rearrangement through interatomic electronic transitions before 1s hole filling for fluorine Kα emission. The emission spectra of LaF3 and CeF3 are compared with the XPS spectra of the F- 2p valence bands obtained by Sato. There is a good agreement between them.
