abstract = {Crystal structures of hydrothermally synthesized BiEuWO6
and BiTbWO6 nanomaterials are deduced for the first time by
combined Rietveld refinement of neutron and synchrotron data
using the ordered and disordered models available in
literature. The ordered model is validated for the average
structure of these nanomaterials, and it is further
supported by the local structure analysis using neutron pair
distribution function. Nanomaterials are characterized by
field-emission scanning electron microscopy, transmission
electron microscopy, Brunauer–Emmett–Teller surface
area, diffused reflectance spectroscopy, and Raman
Spectroscopy. Rare-earth-substituted nanomaterials are found
to be efficient photocatalysts over the parent Bi2WO6 under
visible light irradiation for Congo-red dye degradation.
Particularly, BiTbWO6 shows an enhanced photocatalytic (PC)
activity compared to BiEuWO6, as evidenced from the
photoelectrochemical and time-resolved fluorescence studies.
The difference in the observed PC activity of these
nanomaterials is also explored through a detailed comparison
of crystal structure and electronic structure calculated
through the density functional theory method.},
