Analysis of the Absorption Spectrum of U3+ Doped YCl3 Single Crystals

Sobczyk M., Drożdżyński J., Karbowiak M.

Polish Journal of Chemistry

2005

Vol. 79 / nr 11

1805-1811

Low-temperature emission and polarized absorption spectra of U3+ ions diluted in YCl3 host single crystals have been recorded in the 4000-50000 cm-1 spec tral range. The point symmetry of the doped U3+ ions has been assumed to be octahedral. 29 ex perimental crystal-field levels were fitted to seven parameters of a semi-empirical Hamiltonian represent ing the combined atomic, and one-electron crystal field operators, with arms deviations of 49 cm-1.
