Structural characterization and photoluminescence of nanocrystalline Ho-doped BaTiO3 derived from sol–gel method
ABSTRACT Nanocrystalline Ho-doped BaTiO3, with average nanocrystals size of 20nm, have been prepared using a sol–gel combustion technique. The structural and morphological
properties of the powders have been investigated by X-ray powder diffraction and high resolution transmission electron microscopy.
Chemical states of the holmium on the Ba0.97Ho0.03TiO3 ceramic surface were analyzed using X-ray photoelectron spectroscopy. Furthermore, their photoluminescence properties were
