Determination of the local site occupancy of Eu3+ ions in ZnAl2O4 nanocrystalline powders
(Elsevier B.V., 2011-06-01)
Once lanthanides-doped ZnAl2O4 have attracted attention for highly efficient phosphors and due to the complexity of this system, this work is focused in the understanding of the local site occupancy of the doped ions in ...

Spectroscopic characterization of 2-amino-N-hexadecyl-benzamide (AHBA), a new fluorescence probe for membranes
(Elsevier B.V., 2006-11-20)
We report the results of investigation on the spectroscopic properties of a new fluorescent lipophylic probe. the fluorophore o-aminobenzoic acid was covalently bound to the acyl chain hexadecylamine, producing the compound ...
Energy transfer between terbium and europium ions in barium orthosilicate phosphors obtained from sol-gel route
(Elsevier B.V., 2018-07-01)
The present paper reports on the energy transfer mechanism between Eu3+ and Tb3+ in barium orthosilicate obtained from the sol-gel route, when both activators concentration is varied. The synthetic methodology was adjusted ...
Probing the effects of oxygen-related defects on the optical and luminescence properties in CaCu3Ti4O12 ceramics
(2018-12-01)
The formation of oxygen-related lattice defects and their influence on optical and electronic properties in CaCu3Ti4O12 (CCTO) ceramics were studied by controlling the oxygen partial pressure during the sintering process ...
