|Abstract:||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 di raction analysis and fluorescence spectroscopy. The phase composition and luminescent properties of these LDHs were investigated and discussed. The Ln3+ substitution e ects were investigated in the Mg3Al1−xLnx LDHs by changing the Ln3+ 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|
