| 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 Ln3+ substitution effects 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. |
