Characterization of Barium Titanate Ceramic Powders by Raman Spectroscopy
(Polish Acad Sciences Inst Physics, Warsaw, 2009)
Barium titanate, BaTiO3 ceramic powders were prepared by mechanochemical synthesis and by the Pechini method. A powder mixture of BaO and TiO2 was treated in a planetary ball mill in an air atmosphere for Lip to 1 h, using ...
La-doped and La/Mn-co-doped Barium Titanate Ceramics
(Acta Physica Polonica A, 2013)
Barium titanate ceramics doped with 0.3 mol.% lanthanum and co-doped with 0.3 mol.% lanthanum and 0.05 mol.% manganese were investigated. The powders were prepared by a modified polymeric precursor method based on the ...
The effects of nonstoichiometry on optical properties of oxide nanopowders
(Polish Academy of Sciences, 2007)
In this paper we illustrate the change of optical properties of mechanically activated wurtzite ZnO powder and laser synthesized anatase TiO2 nanopowder due to the nonstoichiometry caused by mechanical activation and/or ...
Effects of Ag+ Ion Doping on UV Radiation Absorption and Luminescence Profiles of Fluorapatite Nanomaterials Obtained by Neutralization Method
(Polish Acad Sciences Inst Physics, Warsaw, 2019)
In the present study we have analyzed effects of Ag+ ions doping on energetic profiles of nanophosphors materials based on fluorapatite crystal system. The UV radiation absorption and luminescence properties of monophase ...
