Abstract: The optical absorption and luminescence spectra of the uranyl-doped fluorophosphate glasses 75NaPO(3)-24.5SrF(2)-0.5UO(2)F(2) and 60NaPO(3)-24.5SrF(2)-15LiF-0.5UO(2)F(2) are discussed. The absorption spectrum of the uranyl ion in glasses shows less fine structure than the spectra of uranyl complexes in solution. The glass samples exhibit a strong luminescence typical for the uranyl ion, and the luminescence spectrum is well resolved. It was found that the force constant of the vibrations in the ground state is intermediate between that in fluoride and phosphate glasses. During the glass preparation, reduction of uranyl to tetravalent uranium is often observed.
