Artykuł
Low temperature emission and polarized absorption spectra of U3+ ions diluted in YCl3 host single crystals have been recorded in the 4000-500000 cm-1 spectral range. The point symmetry of the doped U3+ ions has been assumed to be octahedral. 29 experimental crystal-field levels were fitted to seven parameters of a semi-empirical Hamiltonian representing the combined atomic, and one-electron crystal field operators, with a rms deviation of 49 cm-1.
