A series of sodium borosilicate glasses containing cesium, molybdenum, and chromium was prepared to investigate the partitioning of chromium amongst the glass and phase-separated crystalline molybdates. The precipitates were examined by (133)Cs, (23)Na, and (95)Mo MAS NMR, revealing a phase assemblage consisting of Na(2)MoO(4), Na(2)MoO(4)·2H(2)O, Cs(2)MoO(4), Cs(2)CrO(4), CsNaMoO(4)·2H(2)O, an...

Femtosecond (fs) laser writing is a flexible way to induce three-dimensional local structural modifications inside glass materials, such as crystallization. The latter function of both composition, hence properties, and parameters. Previous works have shown that composition 33Li 2 O–33Nb O 5 –13SiO –21B 3 (LNSB) mol% yields crystallization polarization orientable LiNbO nanocrystals upon irradia...

The leaching behavior and structure of Li2O-CeO2Fe2O3-P2O5 glasses incorporated with simulated high level nuclear wastes (HLW) were studied. The leach rates of gross and each constituent element were determined from the total weight loss of the specimen and the leachate analyses by inductively coupled argon plasma spectroscopy (ICP). The gross leach rate of the 4.5Li2O9.7CeO2-34.7Fe2O3-51.5P2O5...

We present photoluminescence properties of Tb(3+) doped borosilicate glasses modified by Cu(+). Around 5-time enhanced emission at 541 nm due to the superposed emission of Tb(3+) and Cu(+) is observed under the deep UV excitation. Excitation spectra demonstrate a greatly increased absorption of Tb(3+) ions in the deep UV region towards the Cu(+) excitation band, while the shortened Cu(+) emissi...
