dc.description.abstractEu(III), Tb(III) and Eu(III)/Tb(III)-doped Y2O3 nanosheets and nanorods were prepared by hydrothermal synthesis and post-thermal treatment. Their morphology, crystallinity, photoluminescence and UV-visible absorption profiles were fully examined by scanning electron microscopy (SEM), X-ray diffraction (XRD) crystallography, photoluminescence imaging and UV-vis absorption spectroscopy. The as-prepared samples commonly showed the crystal structure of Y4O(OH)(9)NO3, which crystallized to cubic phase Y2O3 after 550 degrees C-thermal annealing. The sharp emissions of Eu(III) between 580 and 720 nm were attributed to D-5(0) --> F-7(J) (J = 0,1,2,3,4) transitions, and those of Tb(III) between 450 and 720 nm were attributed to D-5(4) --> F-7(J) (J = 6,5,4,3) transitions. Energy transfer from Tb(III) to Eu(III) was confirmed by the photoluminescence decay dynamics. In the cubic Y2O3 structure, Eu(III) was embedded at the C-2 symmetry site and dominated by the D-5(0) --> F-7(2) transition. Conversely, Tb(III) was oxidized to non-luminescent Tb(IV) in the cubic structure. (C) 2014 Elsevier B.V. All rights reserved.-
