5th International Conference on Oxide Materials for Electronic Engineering - Fabrication, Properties and Applications (OMEE) -- MAY 29-JUN 02, 2017 -- -- Lviv, UKRAINE ; WOS: 000431684900030 ; Mg/Al/Ln (Ln = Nd, Sm, Eu) layered double hydroxides (LDHs) were synthesized using sol gel method for the first time to the best our knowledge. The obtained materials were characterized by X-ray diffraction analysis and fluorescence spectroscopy. The phase composition and luminescent properties of these LDHs were investigated and discussed. The Ln(3+) substitution effects were investigated in the Mg(3)Al(1-x)Ln(x) LDHs by changing the Ln(3+) concentration in the metal cation layers up to 10 mol%. It was demonstrated that only Mg3Al1-xEux LDHs showed luminescence properties, however, no any light emission was observed for the Mg3Al1-xNdx and Mg3Al1-xSmx LDH samples. ; Lviv Polytechn Natl Univ, Sci Res Co Electron Carat, Polish Acad Sci, Inst Phys, Representat Off Polish Acad Sci, Int Ctr Diffract Data ; European Union's Horizon research and innovation programme under the Marie Sklodowska-Curie grantEuropean Union (EU) [645660] ; The work has been done in frame of the project TUMOCS.
