Abstract

The analysis of allowed electronic transitions in thin films of the disordered ionic compounds MgF₂ and AlF₃ was obtained by optical absorption studies in the uv region. The results are given as a function of the composition and of the degree of crystallization of the films. The characterization of the samples resulting from nuclear analysis (Rutherford backscattering and α–X reactions), intramolecular vibrations (ir absorption), and x-ray diffraction studies are reported.
