Description
Speciation studies of U and Am in alkali barium borosilicate glasses, prepared via sol-gel route were carried out using time resolved photoluminescence (TRPLS) spectroscopic technique. The PL spectrum of the uranium containing glass showed green emission band at 540 nm without any vibronic structure along with excitation peaks at 275, 323, 348 and 412 nm. These data indicated the presence of uranium as uranate (UO6)6- in the glass matrix. Am was stabilized in the matrix in its trivalent form which was confirmed from its excitation, emission and decay time data. (author)
