Abstract

We examined the migration of uranium atoms in uranium glasses after applying the electric field of 5-15kV/mm at RT and at 373K using the technique of Rutherford backscattering (RBS). After applying the electric field of 10kV/mm between the front surface and the back surface of the glasses (1mm in thickness) at 373K for 2 hours, there was neither enhancement nor depression in the concentration of uranium atoms at both surfaces of the negative charge or of the positive charge. In addition, we examined some optical properties such as optical absorption, photoluminescence, photoluminescence excitation and the decay properties of the photoluminescence of the uranium glasses. The optical absorption showed intense absorptions below 345nm and three peaks at 416nm, 482nm and 706nm. The luminescence excited by 416nm light showed four peaks at 512nm, 52Snm, 556nm and 584nm. A decay time determined by the forth harmonic light (266nm) of Nd:YAG laser is about 250 μs.
