Abstract
The ion-beam induced changes in the characteristics of gadolinium doped ceria (GDC) pellets have been studied by UV-visible spectroscopy (UV-vis), SEM, and XRD. Implanted ions were protons or Xe ions with the energy of 120 keV or 5 MeV. Densely sintered pristine GDC pellets have cubic fluorite structure and are brown in color. As the ion irradiation proceeded, its color gradually turned into light black and finally into dark black. XRD patterns of GDC pellets were closely related with ion energy and the penetration depth of X-ray. It showed that upon the ion irradiation (120 keV) the lattice parameter of the cubic fluorite phase just beneath the surface is increased.
