Structural characterization and photoluminescence of nanocrystalline Ho-doped BaTiO3 derived from sol–gel method

Journal of Nanoparticle Research (impact factor: 3.29). 05/2012; 13(8):3123-3128. DOI:10.1007/s11051-011-0224-3 pp.3123-3128

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
analyzed.
